N2 - In this paper, we describe the design and in-vivo testing of a wireless, battery-free implant that is fabricated on a 100 μ m-thick parylene/PDMS substrate with dimensions of 15.6 ×6.6 mm2. The benchtop test shows that the device can generate monophasic voltage pulses with an amplitude of 20 V at a distance of 25 mm from an RF transmitter, and the frequency and width of these pulses can be externally controlled. The implant's operation was verified in-vivo by generating high-amplitude voltage pulses (8 V) and injecting adequate current (≈ 2 mA) into the motor cortex, leading to a motor response in a rat model. These results demonstrate the implant's ability to eliminate the need for batteries and wires and deliver electrical stimulation.
