Demand for miniaturized and long-lasting power sources is increasing in biomedical applications as wearable and implanted devices are becoming more prevalent. The scaling of CMOS feature sizes, supply voltages, power budgets, and the desire for systems to be wireless and operational for years without frequent battery replacement has increased the utility of energy harvesting as a potential power source. Inductive charging is widely used to transfer energy to biomedical implants to transcend volume and operating lifetime limitations imposed by batteries. Optical power transfer using integrated photovoltaics is an emerging alternative that can decrease the implant volume while being MRI-compatible, but is potentially limited by low power density and low optical transmittance through tissue.
