Using an Arduino Nano, ultrasonic sensor, and buzzer, it can sense objects in their ... Let’s start to design the circuit diagram for our Smart Blind Stick. The below circuit diagram shows the ...

Abstract: In this study, we use piezoelectric materials to overcome the high-impedance and electromagnetic interference susceptibility of piezoelectric micromachined ultrasonic transducers ... and ...

Abstract: In this work, a piezoelectric-capacitive hybrid micromachined ultrasonic transducer (HMUT) with a high round-trip gain was developed to achieve superior pulse-echo imaging performance.

Not so, if you use a pair of specialised ultrasonic transducer arrays to move the air instead! (Video, embedded below) Three banks of thrusters provide a 180 degree steerable net force Details are ...
