Abstract:
1. A nerve-stimulating and signal-monitoring device, wirelessly coupled to a monitor station, the nerve-stimulating and signal-monitoring device comprising: a flexible substrate; a modulation/demodulation module disposed on the flexible substrate, configured to demodulate a coded nerve-stimulating radio-frequency signal or to modulate a coded epidermal nerve response signal; an antenna formed on the flexible substrate, coupled to the modulation/demodulation module; a system on chip (SOC) unit coupled to the modulation/demodulation module, wherein the SOC unit decodes and transforms the nerve-stimulating coded signal to obtain a nerve-stimulating electrical probe-driving signal, and/or the SOC unit receives, amplifies, analyzes, classifies and encodes an epidermal nerve response signal, which is then sent to the modulation/demodulation module for modulating and is subsequently transmitted using the antenna to the monitor station for monitoring and analysis; a plurality of stimulation probes protruding from the flexible substrate and electrically coupled to the SOC unit, configured to transmit the nerve-stimulating electrical probe-driving signal and/or the epidermal nerve response signal; and a thin film capacitor configured to adjust a resonant frequency of the antenna, wherein the thin film capacitor is formed on the flexible substrate and is coupled to the antenna; wherein the thin film capacitor comprises a lower electrode of doped p-type poly-silicon, an upper electrode, and a dielectric layer disposed between the lower electrode and the upper electrode.
