A piezoelectric microelectromechanical system (piezoMEMS) is a miniature or microscopic device that uses piezoelectricity to generate motion and carry out its tasks. It is a microelectromechanical system that takes advantage of an electrical potential that appears under mechanical stress.
Quartz is one member of a family of crystals that experience the piezoelectric effect.The piezoelectric effect has found applications in high power sources, sensors, actuators, frequency standards, motors, etc., and the relationship between applied voltage and mechanical deformation is well known; this allows probing an acoustic resonance by electrical means.
One of the examples of a swimming microrobot is a helical magnetic microrobot consisting of a spiral tail and a magnetic head body. This design is inspired by the flagellar motion of bacteria. By applying a magnetic torque to a helical microrobot within a low-intensity rotating magnetic field, the rotation can be transformed into linear motion.

These microcontrollers were originally developed by Cygnal. In 2012, the company introduced ARM-based mixed-signal MCUs with very low power and USB options, supported by free Eclipse-based tools. The company acquired Energy Micro in 2013 and now offers a number of ARM-based 32-bit microcontrollers. 8-bit C8051; EFM8 series; 32-bit ARM Cortex-M0 ...
These processes typically include depositing a film, patterning the film with the desired micro features, and removing (or etching) portions of the film. Thin film metrology is used typically during each of these individual process steps, to ensure the film structure has the desired characteristics in terms of thickness ( t ), refractive index ...
Luigi Mangione arrived at a Pennsylvania courthouse on Thursday for his latest hearing welcomed by at least 100 protesters who gathered in support of the alleged assassin.
If you'd instead put your $10,000 into an S&P 500 (SNPINDEX: ^GSPC) index fund, you would've had just $11,900 at the end of the year. An equal investment in an S&P 500 index fund would be worth ...
