Researchers out there have managed to come up with a film polymer sensor that generates voltage when being bent, with the voltage generated depending on the degree of the bend. One of features of this sensor is that the output is maintained at an almost constant rate when it’s being bent and does not require a power supply. The shape and size of the sensor can be changed, depending on the application and required voltage value. The company expects the sensor to be used for medical devices and various input devices with the size of the market for this sensor estimated at $1.2 billion per year on a global basis. The company, Kuraray Co Ltd, will be exhibiting the sensor at the Sensor Expo Japan 2010.
