Sense of touch belongs to one of the five Human Senses. Whereas blind people largely use feeling in everyday life, sighted person mainly focus on hearing and vision. However, haptic interface started being introduced in customers applications, such as smar ...
Piezoelectric actuators are widely used in industry, especially for their high-speed response and large force generation. In practice, a Piezoelectric Actuator Drive (PAD) is a crucial point to ensure the performance of the actuator. Our current applicatio ...
High-speed laser manipulation is a key technology in applications such as fast optical switches for coupling light into optical fibres, 2D beam steering for optical scanners, laser printers or 2D sensors. A novel design of a Polyvinylidene Fluoride (PVDF) ...

This paper describes a system to drive piezoelectric actuators over more than one decade of voltages and one octave of frequencies, in order to perform high-speed complex impedance characterization at a user chosen voltage excitation level. This characteri ...
Nowadays many consumer electronic devices are using small engines (micromotors). Thanks to technological innovation, the components can be imbedded into numerous portable systems. The key factors for a nomadic integration are: reduction of power consumptio ...
Piezoelectric motors are particular motors converting electrical energy into mechanical movement, based on the inverse piezoelectric effect. Piezoelectric material, when electrical field applied, produces acoustic or ultrasonic vibrations. These vibrations ...
Micronozzles with piezoelectric actuator were fabricated and investigated. The micronozzles were fabricated in glass substrates using a powderblasting technique, and the actuator is a bimorph structure made from a piezoelectric polymer. The actuator was lo ...
NOVELTY - The microscope (11) has a set of four actuators (14, 16, 18, 20) i.e. piezoelectric actuators, and a strain gauge coupled to two opposed actuators (14, 18), arranged in opposed push or push-pull configuration to measure the differential motion of ...
A mobile microrobot is defined as a robot with a size ranging from 1 in3 down to 100 µm3 and a motion range of at least several times the robot's length. Mobile microrobots have a great potential for a wide range of mid-term and long-term applications such ...
Anewanalytical modeling approach for piezoelectric bending elements is described. The approach is based on the beam theory under quasi-static equilibrium condition. It uses the theory of superposition of piezoelectric action in the bender and external mome ...
