a Π shape piezoelectric stack actuator (PISA) was designed. One piezoelectric stack and a Π shape metal pedestal were assembled together by a screw to build a PISA. Formula for calculating the ...

This simple STM setup utilises a piezoelectric actuator constructed by deliberately cutting a piezo speaker into four quadrants. With individual drive wires attached to the four quadrants.

Conventional batteries for micro drones are too large and heavy. A solid-state battery, cell switching technology and ...

Actuators are the input and output devices that connect electronic, hydraulic or pneumatic control systems to their environment. They convert external forces or conditions, such as temperature ...
