Flexible pressure sensors have many potential applications in wearable electronics, robotics, health monitoring, and more. In particular, liquid‐metal‐based sensors are especially promising as they can undergo strains of over 200% without failure. However, current liquid‐metal‐based strain sensors are incapable of resolving small pressure changes in the few kPa range, making them unsuitable for applications...
A flexible microfluidic diaphragm pressure sensor using liquid‐metal microchannels is presented by Ali Javey and co‐workers in article number 1701985. The sensor is capable of detecting pressures less than 100 Pa with a resolution of less than 50 Pa. Both heart‐rate monitoring and tactile pressure mapping of a glove with multiple embedded sensors are demonstrated.
