Spider-Man Spidey Sense T-Shirt: My Wallet is Tingling!
Spider-Man’s Spider Sense alerts him to danger and allows his body to react on its own to avoid attacks. Thinkgeek’s Tingling Electronic Spidey Sense T-shirt on the other hand only alerts you when someone – or something – is behind you. But at least you don’t have to get bit by – or look for – a radioactive spider.
Actually there’s nothing special about the T-shirt itself. It comes with a clip-on proximity sensor that also has motors to make it vibrate. When someone approaches at least 5ft. behind you, the device will emit a pulse, emulating Spider-Man’s power. The pulses become more frequent the closer someone is to you. Wait… is this a naughty toy?
I wonder if it will still work if you wear it under a hoodie.
You can pre-order the t-shirt from ThinkGeek for $40 (USD). It won’t be released until October, but I have a feeling it’ll be sold out way before then. I bet tinkerers will be selling replicas of the gadget online before we know it.

Virtual Mobile Keyboard Reads Vibrations, Tests Your Touch Typing
It’s impossible to truly master typing on a tiny touch screen, hence the existence of peripherals like laser keyboards or this iPhone case. But what if your smartphone could use any surface as a keyboard without the help of additional devices? That’s the idea behind the Vibrative Virtual Keyboard.
The software was invented by Florian Kräutli, a Cognitive Computing student at the Goldsmiths University of London. It uses the iPhone’s built-in accelerometer along with a program written by Kräutli to detect which letter has been pressed based on the vibrations made when the user “types” on a flat surface.
Presumably, the app needs to be trained each time it’s used on a different surface or by a different user. I think that even Kräutli himself would admit that the app is unusable as it is. Even without the lag I think it would be far more useful when there are fewer keys involved, perhaps while playing a mobile game. I’d rather have this technology on my phone. Still, the demo does show us just how smart our mobile devices have become.
MIT researchers develop chip that can harvest energy from multiple sources
We've seen a number of different devices that can harvest energy from various sources, but none quite like this new chip developed by a team of MIT researchers. It's able to harvest energy from three different sources simultaneously: light, heat and vibrations. The key to that is a sophisticated control system that's able to rapidly switch between the three sources at all times to prevent any of that energy from going to waste (and not draw too much power itself), with energy from the secondary sources stored in capacitors to be picked up later -- as opposed to existing systems that simply switch between sources based on what's most plentiful. As doctoral student Saurav Bandyopadhyay explains, efficiently managing those disparate sources could be a "big advantage since many of these sources are intermittent and unpredictable," and it could in turn lead to the chip being used in a range of different applications where batteries or existing energy harvesting methods just aren't enough: everything from environmental sensors in remote locations to biomedical devices.

It's hard to tell exactly what Motorola is thinking of here, but it probably isn't a billowing sheet of fabric stretched loosely over the face of a smartphone -- even if that's what it looks like. Instead, this appears to be a patent application for a "free floating display lens" that helps the panel of a mobile device to be used as a Beo-style acoustic speaker. The idea is that you can get louder and less resonant sound without having to dedicate more precious real estate to a larger traditional speaker unit. The application also talks about generating haptic feedback on the lens, using the same underlying piezoelectric structures that would power the audio. Creating vibrations this way could require "eight times" less voltage than current methods while also delivering a higher-amplitude sensation. Merge that with KDDI's weird vibrational speaker technology and the results could be deafening.
