Fiber-based sensors are desirable to provide an immersive experience for users in the human–computer interface. We report a hierarchically porous silver nanowire-bacterial cellulose fiber that can be utilized sensitive detection of both pressure and proximity human fingers. The conductive was synthesized via continuous wet-spinning at speed 20 m/min, with diameter 53 μm, electrical conductivity 1.3 × 104 S/cm, tensile strength 198 MPa, elongation strain 3.0% break. fibers were coaxially...
Abstract Healthcare monitoring systems can provide important health state information by the biomechanical parameter or motion of body segments. Triboelectric nanogenerators (TENGs) as self‐powered sensors have been developed rapidly to convert external mechanical change into electrical signal. However, research effort on using TENGs for multiaxis acceleration sensing is very limited. Moreover, TENG has not demonstrated rotation date. Herein, first time, a 3D symmetric triboelectric...
