MULTI SMART SENSOR DEVICE USING INPUT OF MULTI ENERGY HARVESTING

摘要

The present invention relates to a multi-smart sensor device using multiple inputs of energy harvesting. The technical problem to be solved is to produce and collect electric energy based on photoelectric effect generated by light energy, piezoelectric effect by vibration, electromagnetic induction phenomenon by magnetic field change, improve reliability by multi-sensing, and increase the versatility of use through multiple sensors. According to an embodiment, the multi-smart sensor device includes an energy harvesting unit that produces energy based on a photoelectric effect using light energy, a piezoelectric effect associated with external force, and electromagnetic induction; a power source unit for storing and supplying energy produced through the energy harvesting unit; a sensor unit for detecting a mechanical contact, a contact by magnetic field and metal, and a posture by positional change, respectively; and a communication interface unit for transmitting detected data of the sensor unit to an external receiving apparatus.
