Figure 8. (A) Schematic illustration of artificial electronic sensory skin; (B) Photograph of a 1.2 × 1.2 cm² pristine PPFE film and complete ferroelectric nanogenerator device, respectively, and schematic of the regulating circuit based on ferroelectric nanogenerator; (C) Normalized PSC change of a synaptic transistor under different loading forces, and synaptic weight curves (peak and raw values of EPSC and IPSC) measured with periodical loading forces of 41.3 or 14.2 N at a frequency of 0.67 Hz. All synaptic behavior is measured at |V_DS| = 1.0 V. Reprinted with permission from Ref.^[81]. Copyright 2020, American Chemical Society. EPSC: excitatory postsynaptic current; ferroelectric nanogenerator ; IPSC: inhibitory postsynaptic currents; SWCNT: single-walled carbon nanotubes.
