Bendable Piezo actuators offer deflection in the millimeter range at low force. The ones I have appear to be bimorphic so you need to apply an opposite voltage to each side. The video below is with a 100v supply, current draw seems to be < 1mA. From my reading of the specs they should be able to produce a deflection of ~1.2mm with a 200v drive voltage. However even with the 100v used below you can still clearly see the deflection:\n\n<iframe loading=\"lazy\" width=\"560\" height=\"315\" src=\"\/\/www.youtube.com\/embed\/mFblikJr7r0\" frameborder=\"0\" allowfullscreen><\/iframe><\/p>\n<p>Here a link to the part: <a href=\"http:\/\/www.pantpiezo.com\/productsShow.asp?id=23\">here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I&#8217;ve been playing around with these Piezo actuators which come from pantpiezo (model number QDTE52-7.0-0.77-1).
