Ultrasmall scale implants have recently attracted focus as valuable tools for monitoring both acute and chronic diseases. Semiconductor optical technologies are the key to miniaturizing these devices to the long-sought sub-mm scale, which will enable long-term use of these devices for medical applications. This can also enable the use of multiple implantable devices concurrently to form a true body area network of sensors. We demonstrate optical power transfer techniques and methods to effectively harness this power for implantable devices. Furthermore, we also present methods for optical data transfer from such implants. Simultaneous use of these technologies can result in miniaturized sensing platforms that can allow for large-scale use of such systems in real world applications.
Ultra small scale implants have gained lots of importance for both acute and chronic applications. Optical techniques
hold the key to miniaturizing these devices to long sought sub-mm scale. This will lead towards long term use of these
devices for medically relevant applications. It can also allow using multiple of these devices at the same time and
forming a true body area network of sensors. In this paper, we present optical power transfer to such devices and the
techniques to harness this power for different applications, for example high voltage or high current applications. We
also present methods for wireless data transfer from such implants.
