a Schematic illustration of EPSCs activated by dual-TENGs. b Schematic illustration of CE-activated artificial afferents in dual-TENG mode. c EPSCs activated by single and paired CS actions with spatiotemporal information. d The recorded second EPSCs vs. ΔTpre2-pre1 (interval time between the first and second CS actions). e The recorded EPSC responses to TENG-1 and TENG-2 simultaneously. f The extracted frequencies of the TENG-1 and TENG-2 activations after Fourier transform. The frequencies of the two activation components are clearly extracted from Fig. 4e and Supplementary Fig. 23.
