Published: Feb. 4, 2025

Abstract Bionic neural devices often feature complex structures with multiple interfaces, requiring extensive post‐processing. In this paper, a device intrinsic perception and decision‐making (NDIPD), inspired by neuronal oscillatory activity is introduced. The utilizes alternating signals generated coupling the human body power‐frequency electromagnetic field as both signal source energy source, mimicking activity. peaks valleys of are differentially modulated to replicate baseline shift process in By comparing amplitude NDIPD's electrical output signal, achieves regarding location mechanical stimulation. This accomplished using single interface, which reduces data transmission, simplifies functionality, eliminates need for an external power supply. NDIPD demonstrates low‐pressure detection limit (<0.02 N), fast response time (<20 ms), exceptional stability (>200 000 cycles). It shows great potential applications such game control, UAV navigation, virtual vehicle driving. innovative supply method sensing mechanism expected open new avenues development bionic devices.
