Overview of System showing our three-stage approach to developing a wearable sensor. The first stage involves a calibration step in which the sensor material is measured using a webcam while the electrical response is measured via a set of arduino-based electronics. In the second stage the data is passed to a Long Short Term Memory Neural Network which is trained using part of the data set. In the third stage the sensor is removed from the webcam calibration set-up and embedded in the wearable technology where the live stream of electrical resistance is the only measurement taken - this corresponds to the proposed use case.
