Description

When one need measurement, signal acquisition and wireless transmission, the electronics inevitably needs an adequate supply of operating power. In case of intra-corporeal telemetry device, unless fed extra-corporeally by other means, the operating power must be supported by a local battery there. In this study we devised an intra-corporeal battery system using body fluid available there as presiding electrolyte, to make obvious electronic component “battery” unnecessary in a capsule type sensor-telemeter transmitter. It employs a pair of electrode, magnesium for negative and silver-silver-chloride or carbon positive, placed across the surface of the plastic capsule. Their electrochemical potential difference causes an in-situ primary battery, for example, 1.2V～1.7V, 10～20 microampere capability. A model capsule about 6mm dia. and 12mm length having such electrode cylinders pair electrically separated over core plastic material (poly-oxymethylene(POM), also called poly-acetal or Delrin). In physiological saline water or human urea, the model device operated successfully for more than 24 hours continuously, to conclude a positive feasibility for practical use.
