Capacitive silicone force sensor makes gripping safe and dexterous

The human hand displays a dexterity yet unmatched by technology. Force sensors can close this gap by providing feedback on the grip force, evading damage to delicate and fragile objects such as food and the human body. The Capacitive silicone force sensor SXTSC by Sateco functions according to the capacitive operating principle and can continuously measure touch and compressive force. It is soft and flexible, maybe shaped three-dimensionally, and is ideal for multiple applications in agriculture, electronics, food, surgery and generally in cobots and prosthetics.

Both the sensor's footprint and dimensions may be freely designed. Subsequently, it can be customised to curved surfaces and integrated seamlessly within the body structure and a soft surface. This allows an ergonomic design of robotic grippers, prostheses, and exoskeletons and on small and large surfaces. Used on the surface of a body structure, the material feels comparable to human skin and provides a life-like soft and comfortable human-machine interaction.

The sensor consolidates two measurement functions in one component. It can identify the approximation of a body part at a short distance and precisely measure its exerted force, too. This keeps the combination compact and facilitates predictive operating and measurement systems.

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

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