Murata Manufacturing Co., Ltd. demonstrated the sensor network system using a combination of dye-sensitized solar cells and various sensors at "CEATEC JAPAN 2012". Regarding the dye-sensitized solar cell in this system, Murata Manufacturing Co., Ltd. is promoting the development of its practical use around 2013 to 2014.
The size of the dye-sensitized solar cell displayed this time was the size of a business card, and its thickness was 350 μm, and was formed by connecting eight battery cells in series. A battery module is formed using a combination of dozens of ceramic capacitors for power storage and wireless circuits. At the venue, Murata made use of the module and magnetic sensors to perform a demonstration of detecting the opening and closing of windows and sending notifications to the tablet computer.

Murata has previously demonstrated prototypes of dye-sensitized solar cells at CEATEC. The output power of the products exhibited in 2011 was 5 μW/cm2, which increased to 6-7 μW/cm2 in 2012. Increase the voltage of each cell from 0.4 to 0.5V to 0.45 to 0.55V. The above values ​​are the measurement results of the small area unit. The white LED is used for measurement, and the illumination is set to 200lx.
