This Smart Perch Weighs Birds Without Ever Touching Them

Posted on by

Picture this: you’re a wildlife rescuer trying to nurse an injured falcon back to health. Every few days, you need to catch the bird, restrain it, and place it on a scale. The bird panics, thrashing and screeching. Your heart races as you try not to get talons to the face. Sometimes, the stress alone can kill the very creature you’re trying to save. It’s a nightmare scenario that plays out in rescue centers worldwide, but a team of Korean designers just might have cracked the code on a better way.

Enter PerchCare, a sleek smart perch that’s basically the Fitbit of the bird world, minus all the drama. Created by designers Lee Hanung, Kwon Hyeokwoo, Choi Yoonji, and Kim Minji, this Red Dot Award-winning design tackles a problem most of us never knew existed. But for wildlife rehabilitators, it’s been a persistent thorn in their side for decades.

Here’s the thing about wild birds: they’re masters of disguise when it comes to illness. It’s a survival instinct hardwired into their DNA. In the wild, showing weakness makes you an easy target for predators, so birds will act perfectly fine even when they’re seriously unwell. That’s why tracking their weight becomes absolutely crucial. It’s often the only reliable indicator that something’s wrong before it’s too late. The design team didn’t just dream this up in a vacuum. They spent time interviewing rescuers at the Gyeonggi Northern Wildlife Rescue Center, getting their hands dirty with real-world insights. What they heard was consistent: the current method of weighing birds is dangerous for everyone involved. Birds get stressed to the point of harm, and caretakers risk injury every single time.

So how does PerchCare work its magic? The genius lies in its simplicity. Instead of forcing an unnatural interaction, it turns an everyday object into a monitoring device. Birds need to perch anyway, right? It’s what they do. By embedding weighing technology directly into something that mimics a natural branch, PerchCare lets birds just be birds while quietly collecting vital health data in the background.

The perch itself looks refreshingly minimal, almost Apple-esque in its aesthetic. It comes in multiple sizes to accommodate different species, from tiny songbirds to larger raptors. The mounting system uses suction cups, which means installation is as easy as sticking it to the cage wall. No tools, no complicated setup, no engineering degree required. But the really cool part is how the system communicates. An integrated lighting system provides at-a-glance status updates, while a companion app delivers detailed charts and trends over time. Rescuers can spot concerning weight drops before they become critical, all without ever touching the bird. It’s like having a 24/7 health monitor that doesn’t require awkward vet visits.

The implications here go beyond just making life easier for rescuers (though that alone would be worth celebrating). When you reduce stress during rehabilitation, birds recover faster and more successfully. That means higher release rates back into the wild, which is ultimately the whole point of rescue work. Every bird that makes it back to its natural habitat is a win for biodiversity and ecosystem health.

There’s something beautifully poetic about technology that works by getting out of the way. In our world of constant notifications and flashy interfaces, PerchCare succeeds by being invisible to its primary users. The birds have no idea they’re being monitored. They just land on what feels like a normal perch and go about their business while the tech does its thing quietly in the background. This is design thinking at its finest: identifying a real problem, understanding the needs of all stakeholders (including the non-human ones), and creating a solution that’s both elegant and effective. It’s not about reinventing the wheel or adding unnecessary complexity. Sometimes the best innovations are the ones that feel obvious in hindsight.

VoxeLite Is a Bandage-Thin Patch That Adds Textures to Screens

Posted on by

Screens and headphones already give us high-resolution sight and sound, but touch is still mostly limited to simple buzzes that tell you a notification arrived. That gap makes virtual experiences feel flat, even when the visuals are convincing. VoxeLite is a research project from Northwestern University that brings fingertip-level detail into digital touch, wrapped in a form factor closer to a bandage than a bulky glove.

VoxeLite is a transparent, stretchy patch that wraps around your fingertip like a thin adhesive strip. It’s only a tenth of a millimeter thick and weighs less than a paperclip, but it hides a grid of tiny soft domes that can be turned on and off individually. When you slide your finger across a surface, those domes add patterns of force that feel like bumps, ripples, or directional cues layered over whatever you’re touching.

Designers: Sylvia Tan, Michael A. Peskhin, Roberta L. Klatzky, and J. Edward Colgate (Northwestern University)

The experience works through tiny grabs and releases. As you move your finger, some of the domes gently stick and drag against the surface beneath them, creating little taps or tugs on your skin. Because there are many of them packed closely together and they can switch very fast, the system can draw small icons, arrows, or textures directly on your fingertip. That opens the door to touch-based notifications, tactile emojis, or invisible guides on flat glass.

One of the most important design choices is that VoxeLite is meant to disappear when it’s not active. The soft domes compress and move with your skin, so you can still feel the real texture of a fabric, a button, or a tool handle through the patch. In tests, people could tell rough from smooth materials while wearing it, which is crucial if you want a wearable that stays on during everyday tasks.

On touchscreens, VoxeLite could make virtual buttons feel different from each other, helping you find controls without looking. In AR and VR, it could add the grain of wood, the click of a dial, or the direction of a swipe gesture directly to your finger. For accessibility, it could help blind users trace contours, follow tactile arrows, or feel icons on otherwise flat interfaces that currently offer no feedback.

The research team pushed both how many tactile pixels they could fit and how fast they could update them. The densest version packs more than a hundred actuators into a square centimeter and creates sensations up to hundreds of times per second. In user studies, people could reliably recognize tiny directional patterns and different virtual textures, suggesting that the fingertip can receive surprisingly rich information from such a thin patch.

VoxeLite is still a lab prototype, tethered to external electronics and tested on single fingers. Scaling it up to multiple fingers, making it wireless, and figuring out the best patterns for everyday use are all open questions. It’s a glimpse of what it might feel like when our fingers can sense digital content as clearly as our eyes see pixels, turning touch into a first-class channel instead of an afterthought.

Noise-canceling headphone concept creates sound bubble for clearer conversations

Posted on by

When you need to have a serious conversation with someone or a small group, you probably need to find a place that has a private room or where there will only be a few people. But for times when you have no choice but to have it in a not so quiet place, then you probably wish you had a cone of silence so you can drown out other people’s voices while still being able to hear what your companions are saying.

Designers: Tuochao Chen, Malek Itani, Sefik Emre Eskimez

Well that might soon come true if this concept by the engineers at the University of Washington becomes a reality. The headphones is powered by AI and has the power to filter out the noise from as far as a few feet away so you’ll still be able to hear the conversation around you. It creates an imaginary “sound bubble” so you can focus on what you need to hear.

The noise-canceling headphones has six microphones on its headband, with a small onboard computer running a neural network. It will be able to analyze the distance from various sound sources around you. The ones that are farther away will be filtered out while the sounds closer to you will be amplified. If they come in within your imaginary bubble, you’ll be able to hear them clearly too.

It’s an interesting device to have especially if you have a lot of meetings or conversations outside. It would look strange though to have a group of people talking and all wearing headphones. They are working on smaller versions like earbuds or even hearing aids so that should work better.

Morphing wheel research can ride over uneven surfaces and obstacles

Posted on by

Wheelchairs and mobile robots are useful (and sometimes necessary) tools for those who need them but because of the way their wheels are built, there are a lot of limitations as to where they can go. Uneven surfaces and high obstacle areas can sometimes be unaccessible for them. Researchers have been trying to reinvent the wheel so to speak by coming up with a wheel that can adjust to different terrains. This latest one from Korean researchers may just be the most promising.

Designers: Jae-Young Lee, Seongji Han, Munyu Kim, Yong-Sin Seo, Jongwoo Park, Dong Il Park, Chanhun Park, Hyunuk Seo, Joonho Lee, Hwi-Su Kim, Jeongae Bak, Hugo Rodrigue, Jin-Gyun Kim, Joono Cheong, Sung-Hyuk Song

This Variable-stiffness–morphing wheel that they are testing out is actually inspired by the surface tension of a droplet of liquid. The main thing about this experimental wheel is that it is able to ride through uneven terrain and go through obstacles while still keeping what makes a wheel a wheel when driving through flat ground. You’ll have to go back to your physics notes to fully understand but the basic idea is to create an imbalance in the cohesive forces between molecules.

This deformable wheel that they’re developing has a “smart chain structure” which is a chain of blocks outside the wheel that is connected by wire spokes to opposite sides of the central hub. From the demo video that they showed, the wheel is able to deform and adapt to the surface so it could travel over the obstacles it encounters. The two-wheeled wheelchair they used was able to ride through grassy ground with uneven surfaces. There was not video of the four-wheeled vehicle but they said it was able to drive over rocks and large steps.

It’s still early stages in this research so there are things they need to improve on. For example, dust and particles are able to get through to the smart chain blocks so the wheels are easily damaged. And the video of the wheelchair shows there’s an extreme forward tilt to the chair part so it’s not that safe for passengers yet. But this morphing wheel is promising and may eventually be useful for wheelchairs, mobile robots, and other uses.

Drone quadcopter concept grips power lines to recharge its batteries

Posted on by

Although they may be a bit controversial due to privacy and safety concerns, it’s hard to argue that drones, specifically quadcopter models, have introduced big changes in modern life. Taking photos and recording videos can now have some dramatic flair, and deliveries of food and supplies can be made to harder-to-reach places. What these often astounding use cases don’t always say, however, is that drones have very short operating times due to their small batteries. That means they can only fly over short distances with light payloads unless they stop and land somewhere for a recharge. This research concept tries to think of a different system that takes advantage of one of the most ubiquitous power sources found in most urban areas: heavy-duty power lines.

Designers: Viet Duong Hoang, Frederik Falk Nyboe, Nicolaj Haarhøj Malle, Emad Ebeid

Given our current battery technologies, drones have no choice but to pack light. This means most drones have an operating time of around 1 hour or so, and that’s only if they’re not struggling to keep afloat with a heavy load. This drastically shortens the travel time and distance of drones unless they find a way to charge en route, almost like how a car refuels or charges along its way. That, however, would require creating “charging stations” for these drones, which might not always be possible or even economical.

Scientists from the University of Southern Denmark decided to design around a power source that is always there but isn’t solar-powered, which would be too slow and too little for the drone’s use. Instead, the drones clamp onto power lines, the very same thick cables that deliver power from one pole to another. When the drone senses that its battery is too low for comfort, it flies to the nearest power line, flies under a line, and then slowly raises itself until its mechanism grips the line. From there, it uses induction to draw electricity from the line to power that gripping mechanism as well as charge the drone hanging from it.

To test this theory, a drone that was used to inspect power lines was outfitted with custom-made sensors and a gripper before being set to its task without human intervention. The drone recharged itself five times using this method, resulting in an impressive two-hour operation. Although the task put the drone within the immediate vicinity of the electrical line that it needed to recharge, it’s not hard to imagine how delivery drones would likewise have access to nearby lines for the same purpose.

Then again, this recharging system might not be the best solution either, at least given the technologies we have today. Fully autonomous drones are still generally considered to be unreliable, so you can only imagine the fear of one of these flying robots meeting an accident on that power line and taking down a whole block’s electricity. Of course, the better solution would be to have public charging stations like those for cars, but we’re still far from being a drone-centric civilization to warrant such infrastructure.

Smart earrings can read your temperature, paving the way for new wearables

Posted on by

When people talk about wearables or wearable tech, they are mostly thinking of smartwatches and fitness trackers, basically those that are worn on your wrist. Technically speaking, however, any kind of technology that can be worn on your body would qualify as wearables, hence the name, but we have been restrained by the limits of current technologies and design trends. Fortunately, it isn’t a dead end yet, and smart rings are starting to become a viable alternative, allowing some people to still keep track of their health while finally being able to wear their favorite classic watches again. These rings reveal the potential of jewelry that could deliver those same features while allowing you to maintain your fashion sense, like this earring that can read your body temperature, something that is still uncommon even on smartwatches today.

Designers: Qiuyue (Shirley) Xue, Yujia (Nancy) Liu, Joseph Breda, Vikram Iyer, Shwetak Patel, Mastafa Springston (University of Washington)

Our bodies are a treasure trove of data, depending on which part you are observing. Smartwatches try to shed light on our health by literally shining light through the skin on our wrists and down to blood vessels. Smart rings largely do the same, though on your finger, of course. While much of your body’s state can be calculated from these areas, some body parts give more accurate biometrics than others. There might still be some debate about it, but some researchers believe that the ears, particularly our earlobes, are a better source for that kind of information.

That’s the medical foundation that the Thermal Earrings are based on, a research project that is attempting to create a new wearable that is both functional and potentially fashionable, especially for women. The device uses two sensors, one that magnetically clips to the earlobe and measures body temperature, while another dangles an inch below it to measure room temperature. Comparing data from these two sources yields a more accurate body temperature reading compared to smartwatches that can’t properly differentiate ambient temperature. This accurate reading is crucial not just for knowing your body’s temperature but, for women, also for keeping track of their ovulation and periods.

The Thermal Earrings’ diminutive design presents both a challenge and an opportunity. It uses up very little power and uses low-power Bluetooth to transmit its data to a paired smartphone. In theory, it can be charged with solar or kinetic energy, but implementing a charging system for that is proving to be a bit tricky. And since only one earring is enough to read the wearer’s body temperature, it raises the question of what the other earring would do. Should it be a simple non-smart decoy to pair with the smart earring or can it also be used to read some other biometric as well?

More importantly, however, the Thermal Earrings open the doors to another kind of wearable accessory. Although the current prototype is largely limited by the electronics it uses, it can already be customized with charms and gemstones. More research into different materials and forms can hopefully lead to more chic styles, ones that ladies won’t be embarrassed to be seen wearing.
