Development of a Flexible Displacement Sensor Using Nylon String Coated with Carbon and Its Application for McKibben Actuator

The actuators for such a wearable device need to be flexible so as not to injure the body. The purpose of our study is to develop a flexible and lightweight actuator and a compact control device that can be safe and light enough to be attached to the human body. In this study, we proposed and tested a new type of flexible potentiometer using nylon string coated with carbon. As a result, we found that the tested sensor that can detect the displacement of the McKibben actuator so as not to lose the flexibility of the actuator
