Patent number: 10898736Abstract: Described herein are implantable devices configured to emit an electrical pulse. An exemplary implantable device includes an ultrasonic transducer configured to receive ultrasonic waves that power the implantable device and encode a trigger signal; a first electrode and a second electrode configured to be in electrical communication with a tissue and emit an electrical pulse to the tissue in response to the trigger signal; and an integrated circuit comprising an energy storage circuit. Also described are systems that include one or more implantable device and an interrogator configured to operate the one or more implantable devices. Further described is a closed loop system that includes a first device configured to detect a signal, an interrogator configured to emit a trigger signal in response to the detected signal, and an implantable device configured to emit an electrical pulse in response to receiving the trigger signal.Type: GrantFiled: May 1, 2019Date of Patent: January 26, 2021Assignee: The Regents of the University of CaliforniaInventors: Michel M. Maharbiz, Dongjin Seo, Konlin Shen, Jose M. Carmena, Ryan Neely, Elad Alon, Jan Rabaey
