atchikom pressure and the porous coating.

principle of operation is based on a simple chemical reaction: in the gastro-intestinal
ischemia (poor circulation) in the stomach of accumulated carbon dioxide
. The gas penetrates into the gel in the polymer increases the pressure that
captures sensor. A sensor sends a radio signal doctor.

Due to its small size (2,9 x0, 9h0, 7 mm) probe is easily installed in the nose
thin catheter. The probe is held in the stomach, and
sensor can work there for several days. In addition, the sensor can be
modified to measure the concentrations of other substances in the body,
such as glucose or some of the ions.
