Physical Insights on Wireless Powering of Deep-Body Ultraminiature Bioelectronics
Résumé
The development of wireless communication and miniaturized electronics has resulted in the emergence of deepbody bioelectronics, which has the potential to significantly enhance the diagnosis, treatment, and monitoring of medical conditions. However, the assimilation of these devices into clinical practice hinges on optimal wireless connectivity and powering. Wireless connectivity is a key feature for real-time data transmission and device regulation within the body. In addition, wireless powering allows for further miniaturizing the devices by removing batteries. However, its implementation is still a challenge due to electromagnetic constraints and the inherent lossy nature of the human tissues. This work analyzes the physical concepts behind wireless connectivity and powering deep-body bioelectronics to address the fundamental bounds on their efficiency and propose novel approaches to enhance their performance.
