The electrical control of the magnetization switching in ferromagnets is highly desired for future spintronic applications. Here we report on hybrid piezoelectric (PZT)/ferromagnetic (Co2FeAl) devices in which the planar Hall voltage in the ferromagnetic layer is tuned solely by piezo voltages. The change of planar Hall voltage is associated with magnetization switching through 90° in the plane...

Piezo ceramics are the key to significant improvements over conventional electromagnetic motors for the execution of precise movements with medical equipment. The latest generation piezo ceramic motors and actuators are more compact, require lower voltage, deliver higher torque, have shorter response time, generate less heat, and are nonmagnetic and vacuum compatible compared to EM motors. With...

The piezoelectric properties of bone play an important role in the bone remodeling process and can be employed in clinical bone repair. In this study, the piezo-voltage of bone between two surfaces of a bone beam under bending deformation was measured using an ultra-high-input impedance bioamplifier. The influence of shear stress on the signs of piezo-voltages in bone was determined by comparin...

Stimulated by state-of-the-art robotic and computer technology, Intra Cytoplasmic Sperm Injection (ICSI) automation aims to scale and seamlessly transfer the human hand movements into more precise and fast movements of the micro manipulator. Piezo-drill cell injection, a novel technique using piezo-driven pipettes with a very small mercury column, has significantly improves the survival rates o...

In the present paper the thermodynamic and phenomenological descriptions of the crossflow piezo-electrooptic effect in crystals have been made. For example the necessary experimental measurements of this effect have been carried out in the lithium tantalate crystals. For these crystals at first the P33113−P11113 = −4.6·10 m/ N·V absolute coefficients difference of crossflow piezo-electrooptic e...

Sperm immobilization prior to intracytoplasmic sperm injection (ICSI) is thought to be necessary for efficient fertilization. A variety of methods of sperm immobilization (pipetting, squeezing and piezo application) are currently employed in ICSI. The effect of differences in immobilization method on the timing of initial Ca(2+) oscillations of oocytes in ICSI was investigated. Motile spermatoz...

CTS began manufacturing pointing devices in 1994 for use as cursor controls, mounted in the keyboards of notebook computers. While completed keyboards were robust against ESD, many precautions were required during manufacture and assembly to protect against the effects of ESD. While these ESD “protective” controls were effective in controlling ESD, they did not eliminate the ESD susceptibility ...
