Capacitive silicone force sensor SXTSC by Sateco - the intelligent electronic skin

Through its subsidiary, Sateco XT AG, Sateco is breaking new ground and adding the capacitive silicone sensor SXTSC to its portfolio of established keypad systems. The elastomer sensor works according to the capacitive operating principle and can continuously measure both touch and compressive force. It is soft and flexible, can be shaped three-dimensionally, and is suitable for various applications such as automotive, VR, AR, gaming, robotics, medical technology and general industry.

Both the sensor's footprint and dimensions can be freely designed. As a result, it can be customized to curved surfaces and integrated seamlessly between the body structure and surface. This enables an ergonomic design of input devices, prostheses and exoskeletons both on small and large surfaces.

The sensor combines two measurement functions in one component. It can detect the approximation of a body part at a short distance and precisely measure its exerted force as well. This keeps the combination compact and enables predictive operating and measurement systems.

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

When used as a measuring cell, the sensor can be easily integrated directly in the surface away from a circuit board using electrical connectors. Its elastomer material makes additional damping, preload and tolerance compensation elements unnecessary. This simplifies the design and reduces manufacturing costs.

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

Samples including evaluation electronics are available in a starter kit and enable a quick and uncomplicated start into the new technology.
