4. Flexible Triboelectric Nanogenerators: Principle and Fabrication

This chapter investigates the following five aspects: (I) It utilized the micro-nanointegrated fabrication technology mentioned above to fabricate nanogenerators and realized a novel high-performance sandwich-shaped triboelectric nanogenerator (TENG); (II) it established the theory model for three-layer TENG and obtained the numerical analysis of the device’s electric output based on this model; (III) it thoroughly analyzed the working principle of sandwich-shaped TENG using the finite element method; (IV) it systematically tested its electric output performance and deeply studied the influence of frequency of applied force and the size of the device on device’s output performance; and (V) it explored the performance of this sandwich-shaped TENG under different loads and validated its long-term stability and continuously working ability.
