Miniature pressure acquisition microsystem for wireless in vivo measurements

Abstract

Improvement of therapies and diagnosis methods require the acquisition of clinical data with optimal accuracy and reliability. Combination of recent progresses in SOI micro machining and telemetry lead to the development of a new miniature pressure sensor acquisition microsystem to be inserted as close as possible to the organ or the targeted area. Moreover a wireless RF powering and data transmission has been optimized in order to allow a non-invasive acquisition chain.
