| Outline of Final Research Achievements |
In this study, we aimed to develop an emergency power supply system to implant devices and secondary batteries using the potentials (several decades of millivolts) maintained in our human bodies. In addition, to apply the technique to real biological systems, our research objective also included the development of the real-time recording systems of intercellular and extracellular potentials in the brain and the emergency power source to supply to the implants. Using a DC-DC boost converter circuit, in particular, we proposed the method in which the small potential was boosted, and the set-up potentials were subsequently supplied for the cellular/tissue interfaces including multielectrode array substances and acoustic piezoelectric sensors. As a result, we have developed the boost converter where several decades of millivolts in the DC voltage component was set-up into several volts, which can be used to supply to some electric devices.
