Strain Sensor Fabrication by Means of Laser Carbonization

In this paper, we present the design and implementation of a smart strain based sensory glove for remote control (RC) car applications. This glove would control the RC car with individual finger movements. Laser carbonization was implemented as a fabrication method for developing strain sensors which were integrated on a Polydimethylsiloxane (PDMS) platform. Various sensor designs were fabricated and tested to determine the effectiveness of the glove design. This laser carbonization method resulted in a directional anisotropic characteristic with a relative resistance change of 170× when bent from an angle of 0 ° to 145 ° (complete finger bend).
