Simple piezoelectric-actuated mirror with 180 kHz servo bandwidth.
We present a high bandwidth piezoelectric-actuated mirror for length stabilization of an optical cavity. The actuator displays a transfer function with a flat amplitude response and greater than 135 masculine phase margin up to 200 kHz, allowing a 180 kHz unity gain frequency to be achieved in a closed servo loop. To the best of our knowledge, this actuator has achieved the largest servo bandwi...

متن کاملPiezo-actuated Mouse ICSI (Intracytoplasmic sperm injection)
Intracytoplasmic sperm injection (ICSI) is not only used in human assisted reproduction (ART), but it is also widely employed for veterinary in vitro fertilization during rare species preservation, germ-line rescue of transgenic animals or for any veterinary assisted conception. Piezo-assisted ICSI, which was first described in 1995 [1], can be employed for assisted conception in animals in whi...
متن کاملMulti-body Aeroelastic Analysis of Smart Rotor Blades, Actuated by Means of Embedded Piezo-electric Devices
The paper describes an unusual C beam discretization based on the finite volumes concept. The formulation is developed in the linear (linearised) case first; eventually a non-linear multi-body approach to the same problem, based on previous works [9], is presented. The formulation is generalised to the piezo-electric beam in both cases, with reference to work [10]. Some applications are outline...
متن کاملPrecision Control of a Piezo-Actuated Micro Telemanipulation System
Piezoelectric actuators are widely used in micro manipulation applications. However hysteresis nonlinearity limits accuracy of these actuators. This paper presents a novel approach for utilizing a piezoelectric nano-stage as slave manipulator of a teleoperation system. The Prandtl-Ishlinskii (PI) model is used to model actuator hysteresis in feedforward scheme to cancel out this nonlinearity. T...
