Abstract
This investigation is concerned with the design and modelling of a passive wireless pressure sensor to detect blood pressure inside an abdominal aortic aneurysm sac after endovascular repair of the aneurysm. The sensor consists of a coil and a capacitor to form an inductor–capacitor ( LC) resonant circuit which oscillates electrically at its resonant frequency. This miniature sensor has a size of 6 mm × 6 mm × 1 mm and can be fabricated by microelectromechanical system (MEMS) technology. By activating the sensor with an electromagnetic field, aneurysm sac pressure information can be acquired. The properties and behaviour of this sensor based on computer simulation are also presented in this paper.
