No. 531: Successful development of a technology for low cost production of pressure sensors (June 8, 2012)

Ajinomoto and the National Institute of Advanced Industrial Science and Industry (AIST) jointly developed a technology for low cost production of film pressure sensors. They developed an organic material that generates electricity if pressurized and combined it with the substrate of a plastic on which an electric circuit is printed to produce a film pressure sensor. Because multiple sensors can be aligned vertically and horizontally, it will be easy to build a product with a large area. According to AIST, it will be possible to build a sensor that stretches wall-to-wall, offering such applications as a bed that prevents bedsore and a vehicle seat that provides a high level of comfort.  

Because the new film pressure sensor is printable, the production cost can be reduced to less than several hundredths. It currently costs more than 100,000 yen to produce a 10 cm square pressure sensor, but the newly developed technology can produce a pressure sensor of the same size at a cost from several hundredths to several thousandths of the present cost thanks to the simple production process and lower material cost. If the new film sensor is put on the room or a floor wall-to-wall, it will be possible to monitor the life of an elderly person living alone.
