US Patent 10473539 Stretchable force sensor having undulating patterned electrodes

A force sensor for measuring force and/or pressures disclosed. In some embodiments, the sensor includes first and second layers, each layer having one or more electrodes arranged in a repeating, undulating pattern. Such an undulating pattern may include a serpentine pattern or a repeating v-shaped pattern. When arranged, the one or more electrodes on the first layer are placed in facing relationship and cross the one or more electrodes on the second layer to form a plurality of electrode intersections. When stretched, the one or more electrodes on the first layer move relative to the one or more electrodes on the second layer while creating new electrode intersections.
