Abstract Ultra-compact wireless implantable medical devices are in great demand for healthcare applications, particular neural recording and stimulation. Current technologies based on miniaturized micro-coils suffer from low power transfer efficiency (PTE) not always compliant with the specific absorption rate imposed by Federal Communications Commission. Moreover, current reliant differential of voltage or across space require direct contact between electrode tissue. Here, we show an...
