我々は、安くて簡単な伸縮センサを作る方法を提案する。具体的には光センサをバネに埋め込み、バネが伸縮した際の光の漏れによる反射光の強度を測定することで伸縮率を計測する。
We proposed a fabrication method for stretchable sensor. The stretchable sensor consist of a photo reflector (made up of a photo transistor and an infrared LED) and a spring. The photoreflector is embedded in the spring. When the spring is not stretched, the emitted IR light will reflect back to the phototransistor. However, when the spring is stretched, some of the emitted IR light can flow out through the aperture of the spring, reducing the light reflecting back to the transistor. Therefore, the more the spring is stretched, the less the amount of light would be detected. This method allows user to construct a stretchable sensor that is simple, low-cost and customizable.
