It is a thin, soft and flexible material that outputs a voltage signal proportional to a change in mechanical deformation. Made of silicone rubber sandwiching a dielectric layer of conductive carbon inks, it does not contain any metal parts. Thus it is more lightweight, energy-efficient, accurate and fast to respond compared to traditional rigid and heavy dielectric materials.

The mechanism used for measurement is that the sensors change capacitance when strained, which can be detected. This material can support strain as high as 100% of its own size, and can measure stretch, shock, strain, tensile load, press (compressive loads and pressure), bend (angular loads) and twist (torsional loads).

The material is manufactured by printing electrodes on an elastomeric film and the film is then laminated into a single structure. Standard lengths are 25, 75, 100 and 125 mm (1, 3, 4 and 5 in) and the width, length and thickness can be customized upon request. It is available in black.

Applications include consumer electronics, actuators, sensors, automotive, prosthetic device, medical devices and biomimetic robotics.
