A
bimorph ceramics transducer is attached to the probe to actuate an implant at constant frequency and force amplitude and to detect acceleration response.
(1), used to determine electromechanical characteristics of transducer was developed using method (described in detail in papers [13, 14, 21]) involving implementation of two types of piezoelectric modules to a homogeneous beam: PBS (piezoelectric
bimorph segment) and PTS (piezoelectric triple segment), respectively.
The machines move using a motor called a
bimorph. A
bimorph is an assembly of two materials -- in this case, graphene and glass -- that bends when driven by a stimulus like heat, a chemical reaction or an applied voltage.
In the harvester, the main beam has a proof mass at the free tip; moreover, two beams (piezoelectric
bimorph) are located on top of the main beam just above the proof mass.
The atomizer employed a PZT
bimorph plate attached to a liquid-proof HDPE (high density polyethylene) membrane with a low Young's modulus to generate a pressure wave in the liquid reservoir.
The cantilever transducer has different configurations such as
bimorph, unimorph, and rainbow [23].
Twelve
bimorph transducers were arranged in six rows and two columns, with a gap of 6 mm between each other.
