MEMS pressure sensor: Finger sensing for humanoid robots

KJ4001X1-CA1 The common types of MEMS pressure sensors are capacitive, resistive and piezoelectric, which can be applied to humanoid robot fingers. The working principles of the three types of MEMS pressure sensors are different: 1) Capacitive MEMS pressure sensor: When the sensor is under pressure, the change in the spacing between the upper and lower transverse compartments of the sensor (upper and lower transverse compartments of the sensor) will cause the capacitance change between the partitions, and the pressure can be measured according to the capacitance change; 2) Resistive MEMS pressure sensor: The sensor consists of a base with a silicon film and a resistance structure mounted on it. When the transducer is subjected to pressure, the voltage and the pressure will change proportionally, and the pressure can be measured according to the change. 3) Piezoelectric MEMS pressure sensor: the sensor’s sensitive element is made of piezoelectric material. The surface of the piezoelectric material will generate charge after external force, and the charge will be converted into a power output KJ4001X1-CA1 proportional to the external force through the charge amplifier, the amplification of the measurement circuit and the transformation of the impedance, so that the pressure can be measured. We believe that by integrating flexible MEMS pressure sensors into robotic hands, it is possible to help robots achieve sensitive tactile perception.
