Introduction to tactile sensors for industrial robots

1. Optical tactile sensor

There are two types of optical tactile sensors: inside and outside. In this type, the intensity of the light is adjusted by moving the obstacle to the light path. It has the advantage of being resistant to electromagnetic interference and has a high resolution. Low wiring is required and the electronics are able to move away from the sensors.

2. Piezoelectric tactile sensor

When pressure is applied to the sensor element, the voltage effect on the sensor element is piezoelectric. The occurrence of voltage is directly proportional to the pressure applied. In this case, no external sensor is required. The strengths of such sensors are durability and wide dynamic scale. Able to measure pressure.

3. Resistive tactile sensor

The operation of the sensor is based on the change in resistance between the conductor polymer and the electrode. This type of tactile sensor is widely used. When pressure is applied, the resistance of the conductive material changes. Then measure the resistance. The sensor has the advantages of high durability and good overload tolerance.

4. Capacitive tactile sensor

The capacitance change between the two electrodes is used for capacitive sensors. This type of capacitive sensor measures the capacitance and changes under the applied pressure. The capacitance of a parallel plate capacitor is related to the distance and area of the plate. Capacitors vary depending on the load. The sensor has the advantage of linear response and wide dynamic scale.

5. Magnetic tactile sensor

There are two methods for magnetotactile sensors, one is to measure the change of magnetic flux density, and the other is to change the deformation of magnetic coupling between windings. The sensor has the advantages of high sensitivity and no mechanical hysteresis.
