The capacitive ultrasonic transducer (CMUT) was initially proposed for temperature measurement. A simple CMUT structure and the corresponding matching circuits were designed. Then the effects of ...

PID-based one-axis ball balancing robot using Arduino. Uses an ultrasonic sensor and servo motor to stabilize a ball at a target distance. Real-time tuning of Kp, Ki, Kd via Serial. Includes stability ...

The surface electromyography (sEMG) signal-based human-machine interface (HMI) has been widely used for various scenarios of physical human-robot interaction. However, current HMIs based on bipolar ...

Simultaneously, the wristband uses an ultrasonic sensor array to measure blood pressure and arterial stiffness, while ECG sensors measure heart rate directly from wrist pulses.
