Soft Force Sensors

We have developed soft thin stretchable force sensors that are fully shielded from electrical interference, allowing them to be used widely in soft robotics, worn on the body, and even used near electrical arcs.

The device consists of air and liquid metal channels in a silicone matrix. Force resolution is sub-mN in both normal and shear directions, yet the sensor withstands over 20 N.
