Secual Inc (Shibuya-ku, Tokyo) and Sekisui Chemical Co Ltd co-developed the "Secual Next-generation Security Sensor" by using Sekisui Chemical's film-type dye-sensitized solar cell (film-type DSC).

The sensor is equipped with a primary battery, secondary (rechargeable) battery and film-type DSC. It is powered by electricity generated by the DSC and stores surplus electricity in the secondary battery. It can be used for both crime prevention and elderly monitoring.

The film-type DSC can generate electricity even with an illuminance of 500lx or less. Its thickness is less than 1mm, and its weight is less than 1/10 that of glass. It can be bent and attached to an object.
