Electronic Material Characterisation for Applications in Triboelectric Nanogenerators

摩擦电纳米发电机(TNG)通过耦合接触通电和静电感应来工作，为工业应用提供电力和自供电的传感能力。这项研究涉及设计一种方法，通过在纳米尺度上通过开尔文探针显微镜来表征和优化材料的摩擦电学性能，并通过改进摩擦轰炸仪来在宏观尺度上关联摩擦学和摩擦电学材料的特性。Tengs的三种类型的应用被报道：发电，自供电装置和自供电传感。在设备结构方面，TIGG比电磁发电机灵活得多。具体应用包括自供电麦克风、植入式医疗设备和按键识别。目前的研究集中在优化Tengs的输出特性上。

Triboelectric nanogenerators (TENGs) operate through coupling contact electrification and electrostatic induction to provide power and self-powered sensing capabilities for industry applications. This research involves devising a methodology for characterising and optimising the triboelectric properties of materials through kelvin probe microscopy on the nanoscale, and through modifying a tribometer to correlate tribological and triboelectric material properties on the macroscale.Three types of application for TENGs are reported; power generation, self-powered devices and self-powered sensing. TENGs are considerably more flexible in terms of device construction than electromagnetic generators. Specific applications have included self-powered microphones, implantable medical devices and keystroke identification. Current research focuses on optimising the output characteristics of TENGs.
