A drive and measurement circuit was designed by the author,which meets the require ments presented in [1]:the accelerated fatigue lifetime test is simulated,using actual forces received by the artificial heart valve as parameters. This set of circuits consists of waveform generator, detection and measurement system for the rhythm of the heart, counter for the opening and closing times of the heart valve,as well as large power amplifier. According to the results obtained during operation,it sh...
