Abstract
Abstract A photoelectric transducer advantageously usable as an electrical energy source for driving units of work modules and sensors of a micromachine is provided. This photoelectric transducer is characterized by having a photoelectric transducing element, a self-exciting oscillating circuit, and voltage transformer and optionally further a storage mechanism formed on one substrate. It is further characterized by producing electrical power by the exposure of the photoelectric transducing element to a continuous light.
