The paper gives you information around circuits, the copper circuit, module, circuit, and sensor. Inside the paper we can read information related to comparison, sensors, curvature sensor, and design.
Many things like stretchable circuits, curvature sensors, conductivity, mesh circuit, and actuator module are presented in this paper. The following are grabbed from the paper:
Both the copper circuit and the eGaIn circuit displayed similar responses to folding actuation, but the eGaIn circuit required more power (average power for a full range of motion without external load) to reach the same range of motion with the test module (see Table I).
Additionally, the paper gives the reader information regarding resistance, the curvature sensor, ﬂexible circuits, and power consumption.
