Abstract
The results of a proof-of-concept investigation of using liquid metal as a low-cost alternative to metallic thin films and nanomaterials in a flexible tactile sensor are presented. The liquid metal was deposited using a low-cost and rapid fabrication technique called “liquid-metal spraying.” Commercially available sandpaper was used as a cheap microstructured substrate, and a serpentine channel design was used to maximize the sensitivity of the sensor. The sensitivity of the liquid-metal flexible tactile sensor for both tensile and compressive strain was measured to be less than 0.1, which is an unimpressive value compared to tactile sensors in literature. This result can instead be interpreted as sprayed liquid metal being a suitable material choice for applications where a relatively constant value of resistance is desirable when the device is exposed to strain, such as interconnects and wires in flexible electronics.
