Triboelectric Mechanism for Bidirectional Tactile Sensing and Energy Harvesting

Part of the Springer Theses book series (Springer Theses)


Triboelectric effect has been utilized to realize sensors for various applications e.g. vibration sensing [1], chemical sensing [2–4] and tactile sensing [5–7]. Tactile sensors can be used to sense various type of physical interactions. Various tactile sensors have been proposed based on capacitance [8, 9] and resistance [10, 11], piezoelectric effect [12] and piezophotonic effect [13]. But majority of these sensors have an ability to sense mechanical stimulations in normal direction but unable to sense the shear force stimulations, which severely limits in their application in practical situations. Therefore it becomes imperative to design sensors which can be used for multi directional tactile sensing to gather richer information from the physical interactions
