Mathilde Blondel, a student of France’s Université de Technologie de Compiègne created EVE, personal security and anti-aggression bracelet, after experiencing an assault on the streets of France. In collaboration with friend and colleague Romaric Delahaie, the duo followed EVE through a ten-month period to design the wearable personal security bracelet that’s encrypted with cutting-edge communication technology to provide efficient defense solutions in the face of street attacks.

Once activated, EVE launches a 10-second alarm meant to discourage the attacker from continuing their assault and instantly calls the local police station, sending operators the location and live audio recordings of the attack. EVE follows a two-step activation process to launch the wristband’s emergency features. First, to unlock EVE and prepare it for activation, the user simply shakes their wrist repeatedly three to five times. Embedded inside the wristband, an accelerometer and gyroscope detect the shaking and rotation of the wrist, awakening the device and gearing it up for activation. Then, either by announcing previously recorded voice triggers or by placing pressure on the wristband’s sensors, the 110dB alarm sounds, and the police are called, sending live recordings of the assault to an emergency operator, along with the GPS location of the EVE user.

Blondel and Delahaie designed EVE to be totally autonomous and independent from smartphones so that the functionality of EVE doesn’t depend on a smartphone’s proximity or battery levels. Over a ten-month long period, Blondel and Delahaie sketched and produced multiple prototypes to ultimately settle on a lightweight, small, and accessible wristband whose emergency triggers are easy to activate. Located in the palm of the hand, the sensors that activate emergency departments are easy to trigger and discreet by design.

Designers: Mathilde Blondel & Romaric Delahaie

Discreet by design, EVE is also easy to use and activate.

One charge of EVE can last up to a whole month.

Once activated, either through vocal recognition or sensor technology, EVE launches emergency help from local police officers.

EVE is encrypted with communication technology that functions to launch protective services in the face of street attacks.

The designers behind EVE ensured that the wristband was lightweight and small by design for a comfortable wear.

EVE can be activated by pressing the sensors located in the band that stretches across the palm of the user.

EVE can be activated either through voice triggers or pressure sensors.

Once the pressure sensors are activated, EVE sends out live audio recordings and GPS location to local police operators.

Wrist movement adaption allows EVE to band when the user chooses to unlock emergency services by shaking their wrist three to five times.

Following a ten-month long period of conceptualization and production, EVE ultimately assumed a lightweight body for accessible use.

EVE is equipped with smart technology for instant feedback.
