Figure 5

Hybrid operation of TENG and PENG in three modes: (a) mode I which shares a pair of electrodes; (b) mode II which shares one electrode; (c) mode III which works independently; (d) a textile-based wearable hybrid triboelectric-piezoelectric nanogenerator (TPNG) [77] (reproduced with permission. Copyright Elsevier, 2018); (e) a tribo-piezo hybrid nanogenerator (PTENG) with PVDF/MWCNT/LieZnO as the piezoelectric constituent and PTFE/PDMS as the triboelectric constituent [78] (reproduced with permission.
