Abstract
A telemetric medical sensor for implantation in a patient's body for measuring a parameter therein is provided. The sensor comprises a housing and a membrane at one end of the housing. The membrane is deformable in response to the parameter being measured. A microchip is positioned within the housing and operatively communicates with the membrane for transmitting a digital signal indicative of the parameter. The microchip comprises an array of photoelectric cells for use with an LED for transmitting light at the photoelectric cells. A shutter is connected to the membrane and moveable between the photoelectric cells and the LED in response to deforming of the membrane.
