Cellphone remote intelligent neuroregulation with self-powered piezoelectric wireless brain probe

The neural regulation that is tele-controlled remotely by medical professionals or artificial intelligence (AI) agents can meet the requirement of rapid, precise, personalized intervention and optimize the allocation of medical resources. Here, we develop a new self-powered wireless mini-invasive brain probe for remote intelligent neuroregulation. The probe can be wirelessly powered and controlled by cellphone audio tones (through piezoelectric effect) with the assistance of AI cellphone video analysis. The probe consists of a biocompatible pedestal integrated with implanting stimulation electrodes connected to embedded magnets and a magnetically coupled custom-designed signal-intensifying resonator integrated with a piezoelectric powered signal modulation circuit. A programmed audio tone functions as the wireless power source, and it can be tele-transmitted remotely from other cellphones with desired neural stimulation protocols. Combined with AI-enabled video monitoring of the epileptic tremor, we show that the probe can relieve the seizure events in the epileptic mice, and the therapeutic effect is confirmed by in-vivo electroencephalography and free-moving scenario. The multi-functionality of versatility, AI-assistance, wireless power transfer, and tele-transmission of the cellphone-interacted brain probe opens the possibility for remote precision neural modulation.
