Sensor Stickers Transform the Human Body Into a Multi-Touch Surface

A new skin sensor allows interaction designers to produce skin-like, sensitive multi-touch sensors for any part of the body.

Developed by researchers at Germany's Saarland University, the Multi-Touch Skin sensor features two stacked electrode layers that form a coordinate system. Electrical capacitance is constantly measured at the intersections of the layers, as it drops when touched by a finger.

The new sensor can capture touches from multiple fingertips simultaneously because the changes are sensed at each point of contact.

The research team developed software for designers to create any sensor shape, so it can be made to fit all parts of the body.

The work was presented last month at the ACM Conference on Human Factors in Computing Systems (CHI 2018) in Montreal, Canada.
