Data glove with a force sensor

This paper presents a data glove equipped with a force sensor. The construction and the electronic circuit are also described. The glove is selected to be a rubber-coated cotton glove. The sensors are firmly attached to the rubber-coated glove using cyanoacrilic glue. The force sensor is made of a steel plate substrate where the commercial strain gauges are attached. The plate is attached on the thumb. The strain gauge bridge is powered by a digital current source. A digital sine is produced by a microcontroller and a DAC with current output. At the peak, the microcontroller produces a digital output signal. This signal triggers the data acquisition system. The force sensor presents a linear response and a resolution of 0.38 N with a sensitivity of 0.05 V/N. The combination can be used in robotics, telecheric applications, biomechanics and virtual reality applications.
