Dither piezo
WebEach cantilever chip was mounted onto a dither piezo, excited, and scanned with the Polytec MSA400 system. The plots show the measured vibration spectrum corresponding to the blue square on the cantilever shown on the right. The nomenclature used denotes the type of resonance and the mode number corresponding to that resonance, e.g. B1 ... Websame glue) on a dither piezo plate. This type of the QTF with one prong being fixed is often called qPlus QTF [27]. Another sapphire piece is sandwiched between the dither piezo and the base for good isolation. The oscillation details of the free prong of the QTF are measured by a preamp which is a current to

WebPiezo-actuated platforms are used in several nano positioning applications because of their high resolution, large blocking force, high stiffness constant and quick response. But the intrinsic hysteretic nonlinearity considerably dampens their performance. Dither based control is known to ameliorate hysteresis in piezoelectric actuators. However, due to … WebPiezoelectric Chips and Stacks. Our selection of piezo chips and stacks includes co-fired chips, co-fired stacks, and discrete stacks, as well as stacks with strain-gauges for …
