Energy-Sensing Integrated Device

Due to the limitation of traditional energy supply methods, the development of lowering power consumption and decreasing size of smart electronic devices meet bottlenecks, and the development of new energy supply methods is imperative. Sensors are the basic component of smart electronic devices, which play an important role in lowering the power consumption and decreasing the size of the system. The widely used passive sensors can only be self-powered, they can't supply extra power for other parts of the system, or even for other devices. Since sensors are usually directly applied to environment rich in the potential energy such as mechanical energy and thermal energy, this paper proposes an energy-sensing integrated device (ESID) that integrates energy harvester and sensor, which is used for signal detection, and it can effectively harvest and store ubiquitous energy in the environment. Not only to achieve the function of the device sensor, but also to further supply the harvested energy to other devices in the system, so as to achieve two-in-one between energy-harvester and sensor. In this article, first introduces the principle and system composition of the ESID. Then, this paper designs an energy-sensing integrated counting device (ESICD) based on the mechanical energy of pressure-type to verify the principle of the ESID, and designs the principle prototype. The device collects mechanical energy at the heel of the human body when it is walking to achieve self-supply, and realizes compression motion detection and visualization of detection data. Experimental results show that in specific application environments, the ESID can realize the integration of harvesting energy and signal detection functions, which can solve low-power electronic devices. The ESID is of great significance for the development of intelligent electronic equipment.
