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.

MEMS, wearable/implantable electronics and bio-tissue therapeutics, the pursuit of piezoelectric biomaterials has become a ...

Piezoelectric crystals are a class of materials that exhibit a unique property called piezoelectricity. These crystals generate an electrical charge when subjected to mechanical stress or strain, and ...
