Recently, the "Japan Nano MicroBusiness Exhibition" held a seminar at the Ariake International Exhibition and Exhibition Center in Tokyo, reporting on the achievements and progress plans of the ongoing Japanese government project "Sensor System Development Project for Social Issues." The conference revealed the development process of sensor modules that can be built by simply sticking them on, like a band-aid.
This project aims to develop flexible sensor modules and related technologies with wireless communication capabilities and independent power supply functions. The sensor module can be attached to objects like a band-aid, sensing the surrounding environment and sending data wirelessly, costing about 1,000 yen. Because it is easy to set up and low in cost, it can be widely used in factories, offices, shops, and other locations.
At this seminar, the Green Sensor Network Research Institute under NMEMS Technology Research Organization, a technology research consortium jointly developed with the New Energy Industry Technology Development Organization (NEDO) of Japan, gave presentations. The band-aid sensor module under development features a structure that overlaps flexible antennas equipped with highly integrated MEMS sensors with flexible storage power generation components. The size is 2cm ×5cm, the same as a band-aid, with the thickest part about 1mm thick.
These sensors consist of current/magnetic field sensors, dust sensors, CO2 concentration sensors, VOC (volatile organic compounds) concentration sensors, and infrared array sensors. CO2 concentration sensors measure using ionic liquids that can adsorb CO2. The self-contained power supply consists of color-sensitized photoelectric conversion elements made of organic materials that generate electricity under indoor lighting, along with capacitors. Film-like flexible devices made from organic semiconductor nanofibers are also under development. It is reported that about 80% of the target of 150μW power generation capacity has been achieved. In terms of wireless communication functions, a method suitable for wireless sensor terminals has been developed, capable of low-power communication at around 100 meters and recognizing distances, using spectrum diffusion technology.
Key technologies are currently under development, with samples planned to be completed by March 2014.
