Motion recognition by a liquid filled tubular triboelectric nanogenerator


The development of flexible electronics has extended the limit of the intelligent devices, which are highly sensitive and soft to sustain arbitrary deformation. Here, we report a liquid-polymer tubular triboelectric nanogenerator (L-P TENG) that is filled with liquid for a shape-adaptive sensor in various working modes. The L-P TENG is based on liquid-solid contact electrification with the use of displacement current as excited by the shape change of the tubular structure. The high softness of the device makes it possible to be twisted to any curve and bear an extreme strain. It can be used to detect a slight difference in pressure according to the motion of touch, press and stretching, which is suitable for a wide-range force sensing with high sensitivity. The independent and multifunctional properties of the L-P TENG extend the potential applications through combinations. Such assembled units with crossings can sense the appreciating object. This work provides a new direction for flexible electromechanical sensing and has potential applications in self-powered sensors, wearable electronics, smart human-machine interaction and auxiliary motion correction.
