Madden and Sarwar with sensor prototype
Elastomer sensor prototype
A transparent stretchable touch sensor based on low cost stretchable gel ionic conductors and silicone materials was developed, towards wide applications in soft robotic skin, wearables, and flexible consumer electronics. Transparent tactile sensors based on metal and carbon conductive materials can operate while bent, while our device demonstrates sensitivity to even finger proximity during active bending and stretching. The projected electric field above the sensor couples with and senses a finger. The movement of a finger a few centimeters above the surfaces can be tracked across the array and the approach is adaptable to the detection of proximity, touch and pressure over a wide variety of surface conformations.
