Wireless power sensor network comes out

In recent years, the demand for short-distance wireless sensor networks is expected to continue to increase. As an energy harvesting technology, the proximity wireless sensor does not require a battery or an external power source to convert human or machine vibration into electricity.

Recently, the Takenaka Public Works Store in Japan developed a new wireless sensor network system. The system includes vibration power generation equipment and wireless sensors, does not require batteries and wires, and can convert indoor people's movements and environmental vibrations generated by equipment and equipment into electricity.

The system does not require batteries and wires, and can convert the movement of people in the room and the environmental vibration generated by the equipment and equipment into electricity.

At present, Zhuzhong Public Works Store uses this system in the company's technical research institute to carry out office room temperature and humidity adjustment experiments. This experiment used the micro-vibration of the air-conditioning duct to adjust the temperature and humidity of the office space, confirming the actual operation effect of the system. In the next step, Zhuzhong Public Works Store will negotiate with the equipment manufacturers on the business cooperation and commit themselves to commercial promotion of the technology and system.

This system does not require wiring or use of batteries - this has always been a barrier to the introduction and operation of multiple sensor network systems - and the system can be easily constructed. In addition, visualization of the environment can be achieved through system monitoring built by the system. For example, in a demonstration test of temperature and humidity monitoring in an office space, it can reflect the temperature and humidity data of each office's air conditioner operation. Each office can be connected to a building to be operated uniformly to ensure comfort and satisfaction. And can save energy.

At present, this technology has won the "Engineering Citation Encouragement Special Award" of the Japan Engineering Association Institute. It can not only be used in the field of civil construction, such as monitoring buildings and infrastructure, but also has the potential and versatility of application in the field of disaster prevention, theft prevention, transportation and distribution.
