Implantable sensor simplifies blood pressure readings
"With the new method a tiny pressure sensor, which has a diameter of about 1 millimeter is placed directly into the femoral artery in the groin and measures the patient’s blood pressure 30 times per second. The sensor is connected via a flexible micro-cable to a transponder unit, which is likewise implanted in the groin under the skin. This unit digitizes and encodes the data coming from the micro-sensor and transmits them to an external reading device that patients can wear like a cell phone on their belt. From there, the readings can be forwarded to a monitoring station and analyzed by the doctor. Because the researchers use special components in CMOS technology, the system requires little energy. The micro-implants can be supplied with electricity wirelessly via coils."
