Capacitive silicone force sensor offers intelligent electronic skin

Sateco breaks new ground, adding the capacitive silicone sensor SXTSC to its portfolio of keypad systems. The elastomer sensor operates according to the capacitive operating principle and can continuously measure touch and compressive force. It is soft and flexible, is able to be shaped three-dimensionally, and is ideal for multiple applications, including automotive, AR, VR, robotics, gaming, medical technology and general industry.

The sensor’s footprint and dimensions can be easily designed. As a result, it can be customised to curved surfaces and combined seamlessly between the body structure and surface. This allows an ergonomic design of input devices, prostheses and exoskeletons on small and large surfaces.

The sensor consolidates two measurement functions in one component. It is able to detect the approximation of a body part at a short distance and accurately measure its exerted force as well. This keeps the combination compact and facilitates predictive operating and measurement systems.

Silicone is gentle on the skin. Optional texturing of the surface can make it more comfortable to wear. Silicone is chemical and temperature-resistant concerning food.

Thanks to its elastomer material, the sensor is robust, shock and impact-resistant, and it also provides high durability, even in harsh environments at high (+85C) and low temperatures (-40C).
