Abstract

Is being studied the electrical behavior of sensor made of Velostat under DC and AC voltage and the influence of magnetic field on this sensor type (does not influence). In alternating mode (AC voltage is applied), it starts from the premise that we can easily analyze the current flowing through a resistor of known value inserted with the Velostat sensor and from here we can deduce the behavior of the sensor. To obtain the location feedback of the touch from Velostat sensor, it was built a device which contains discs and circles made of polylactic acid with a 3D printer and double foil of Velostat material on which eight sheets of copper were attached by lamination. An Arduino board is used to inject small currents into the touch sensor but also to read the potential values at the eight terminals formed by the construction. This way we can determine where we touched the sensor.
