Recent developments in soft sensors have shown their capability for complex sensing with high flexibility and stretchability. Unfortunately, current materials and fabrication processes are expensive and complex. There currently exist the need for a more efficient fabrication process of soft sensors for adding touch interactions to physical objects and the human body.

Researchers at Purdue University have developed a single volume sensor capable of sensing real-time continuous contact and stretching. The technology described allows for a low-cost and easy way to fabricate piezoresistive elastomer-based soft sensors by using electrical impedance tomography to estimate changes in resistance. The sensor conducts real-time contact sensing and includes a software toolkit for users to design and deploy personalized interfaces with the sensors.
