EEG Wisp

EEGWISP is  a EEG monitoring system that is battery-free; is powered by a standard UHF RFID reader; and uses backscatter to transmit the data using a EPC Class 1 Gen2 protocol. Since EEGWISP does not need batteries it can be lightweight, miniature and maintenance free for users


This project was supervised and advised by Josh R. Smith at University of Washington
