Abstract

The requirement for electrical power is a major limitation in the development of biosensors for in-body applications. This paper considers motion powered energy harvesting devices for in-body use, showing that power levels are unlikely to exceed a few microwatts for devices of acceptable size. As a low power sensor, we are developing pH detectors based on metal-metal oxide electrodes, such as iridium oxide. The power requirement of these devices is considered, including signal conditioning, storage and transmission. A hybrid powering scheme of energy harvesting and wireless power delivery for data transmission is proposed.
