Abstract

Gastric contractions are coordinated by an underlying bioelectrical activity, termed slow waves. Aberrant slow-wave patterns have been associated with gastric dysmotility. High-resolution mapping of slow waves has potential to detect the mechanisms underlying gastric dysrhythmias. I will present our recent efforts towards the development of wireless implantable systems for gastric slow-wave recording. First, an inductively powered implantable system will be presented along with its shortcomings. Then, a new paradigm will be presented for large-scale gastric interfacing by developing a network of distributed, miniaturized, ultrasonically interrogated implants. Finally, the concept of a new technique for robust ultrasonic beamforming will be presented.
