Abstract

Aim\ To study the measurement of near distance with ultrasonic technology. Methods\ Not only the structural design of ultrasonic transducer that can emit and receive ultrasonic wave by its piezoelectric and innverse piezoelectric effects

but also the driving circuit of the transducer are ontroduced. Results and Conclusion\ The transducer

together with the driving circuit

can emit ultrasonic energy directionally and receive the echo as expected

and can be put into use of various testing applications

such as remote control

measurement of distance and safeguarding.
