Abstract:
We propose a wireless data uplink and localization method for miniaturized sensor implants through magnetic resonance imaging (MRI). Local MRI signals are dynamically modulated by a micro-coil on an integrated circuit (IC). A proof-of-concept chip was designed and tested in a 3T scanner to demonstrate MR image modulation. The proposed uplink approach could enable simultaneous data readout from multiple implants with easy device localization and built-in image registration.
