| New type of logic device uses piezoelectric effect |
| |
|
Researchers claim to have developed a new class of electronic logic device in which current is switched by an electric field generated by the application of mechanical strain to zinc oxide nanowires.
The Georgia Institute of Technology says the devices, which include transistors and diodes, could be used in nanometer-scale robotics, nano-electromechanical systems (nems), micro-electromechanical systems (mems) and microfluidic devices.
According to the researchers, the mechanical action used to ... More

| BLDC motor controller E981.15 with sensorless commutation technique |
| |
|
The new BLDC motor controller E981.15, developed by ELMOS and now available from Gleichmann Electronics, is said to enable a significant reduction of system costs.
The E981.15, which comes in a small 7x7mm QFN package and is based on the patented sensorless VirtuHall principle, controls BLDC/PMSM motors entirely without external sensors. The device includes controller and driver for the control of six N-channel power FETs with PWM frequencies of between 20 and 60kHz and provides numerous error and ... More
