- Intra-Corporeal Sensor-Telemeter with Primary Battery using Body Fluid as Electrolyte
説明
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.
