We are developing soft neural interface platforms that can control neural interfaces and integrate data transmission, signal processing, and power management. These works involve fabrication of flexible electronic systems and development of novel antenna systems and integrated circuit systems. In parallel, we are studying novel methods to maximize wireless power transmission into biological tissues. The followings are ongoing projects.
