![]() ![]() Long operating times are also possible with magnetostrictive ultrasound. The problem with piezoelectric transducers is that they deteriorate very quickly at high temperatures.Ī magnetostrictive ultrasonic system can be used above 100 degrees and still would not wear out. whereas components are usually cleaned at temperature of 40 to 50 degrees.when cleaning molds, temperatures go up to 95 degrees,.But magnetostrictive technology is better suited for cleaning molds and tools.įirst of all, the temperatures for cleaning components are much lower: Yes, we use this technology when there are frequency specifications.įor example, in the components cleaning sector, we have machines that operate with multi-frequency or piezoelectric ultrasound. This means that trasnducers have to be changed every one or two years, which does not apply to our magnetostrictive technology. In this field, the life span of transducers is generally between 40 hours. This is not possible with piezoelectric technology. PMUT has been an active research topic since the late 1990s because of the ultrasound application needs of low cost large 2D arrays, and the promising progresses on piezoelectric thin films, semiconductors, and micro/nano-electromechanical system technology. It is much more efficient and above all, it almost never wears out, unlike piezoelectric transducers.Īs a result, we have magnetostrictive ultrasonic cleaning systems that have been operating for 20 years without problems, and which still work today with the original ultrasonic trasnducer. However, we continued to work on magnetostrictive ultrasound, and we developed our Magnasonic ultrasound. As one of first steps to demonstrate the value of ultrasound-powered piezoelectric neural interface, Li et al. ![]()
