Open-loop printing of liquid metal for the low-cost rapid fabrication of soft sensors

Soft sensors consisting of highly conductive liquid metal, eutectic gallium-indium (eGaIn), embedded in a soft elastomer have been of great interest recently due to their stretchability for sensing temperature, pressure, and strain for a variety of applications. Previous studies have explored methods for patterning the liquid metal during the manufacture of soft sensors. Among these, direct printi...
