A Novel Method of Wireless Micro Energy Transmission Based on MEMS Micro Coil [PDF]

open access: yesMicromachines (Basel), 2023
Based on current implantable devices, a battery’s rigidity and large size makes it prone to immune rejection and wound incisions. Additionally, it is limited by its finite lifespan, which hinders long-term usage. These limitations greatly restrict the development of implantable medical device systems towards miniaturization and minimally invasive ...

The Energy Conversion behind Micro-and Nanomotors [PDF]

open access: yesMicromachines, 2021
Inspired by the autonomously moving organisms in nature, artificially synthesized micro-nano-scale power devices, also called micro-and nanomotors, are proposed. These micro-and nanomotors that can self-propel have been used for biological sensing, environmental remediation, and targeted drug transportation.
