Wire-Free iSoft Flexible Sensors

Oct-26-17 The iSoft, wire-free flexible sensors could have applications in medical devices and clothing.

Developed by a team from Purdue University, the flexible iSoft sensors are made up of carbon-filled silicon rubber, which has natural piezoresistive properties and will change electrical resistance when deformed. This characteristic eliminates the need for wires, and Purdue team overcame a troublesome rebound delay via a dynamic baseline update algorithm.

The iSoft sensors can sense a variety of stimuli in real-time, including continuous contact and stretching, and can be customized relatively easily. According to the team, the sensors could have applications as robotic skin, body motion sensors, and as an interface to control wearable electronics.
