The dynamic response of a piezoelectric cantilever beam under droplet impact is investigated by conducting impact tests. Both droplet dynamic behaviours and voltage output can be acquired simultaneously by means of high-speed camera capturing technique. The surface wettability and the macrotextures affect the voltage generation in different ways. https://www.bekindtopets.com/hot-offer-Stuart-Product-Emcelle-Tocopherol-Vitamin-E-Liquid-1-Liter-hot-value/
