Molded elastic sensors: from scale-up to commercialization

While stretchable electronics is most commonly realized by printing, this presentation shows an alternative approach using proven elastomer molding technology. The design and manufacturing of a soft capacitive sensor is shown which can continuously measure both touch and compressive force. It can be shaped three-dimensionally, and is suitable for various applications such as automotive, VR, AR, gaming, robotics, medical technology and general industry.

The sensor is made of silicone. It's footprint and dimensions can be freely designed. This enables an ergonomic design of input devices, prostheses and exoskeletons both on small and large surfaces. Silicone is gentle on the skin, and is chemical and temperature-resistant with regard to food.

Validation of the sensor is performed by durability tests including up to 500,000 load cycle and rough environmental conditions of +85°C and -40°C. Various use cases towards commercial use are under way, of which some can be communicated here. Samples including evaluation electronics are available in a starter kit and enable a quick and uncomplicated start into the new technology for everyone.
