bimorph

(ˈbaɪmɔːf) or

bimorph cell

n
(Electronics) electronics an assembly of two piezoelectric crystals cemented together so that an applied voltage causes one to expand and the other to contract, converting electrical signals into mechanical energy. Conversely, bending can generate a voltage: used in loudspeakers, gramophone pick-ups, etc

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.
The machines developed by Cornell scientists move using a device known as a bimorph. A bimorph is obtained when two materials react to external stimulus; the team was inspired by origami to combine graphene and glass to create a bimorph that bends with any stimulus like heat, chemical reactions, voltage or just a prod.
A few realizations of this approach were based on straight optical fibers or short fragments thereof correctly attached to the tuning fork or bimorph [15, 16].
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.
To overcome these limitations and further develop the self-powered sensor technique, in this study, the bimorph piezoelectric-cantilever-beam type pressure transducer was used for collecting environment vibration energy.
Twelve bimorph transducers were arranged in six rows and two columns, with a gap of 6 mm between each other.
Also, the muscle can be bimorph. The fibers of the upper portion of the muscle join the superficial fibers of the lower portion to form a thick tendinous lamina that crosses the greater trochanter and inserts into the iliotibial tract of the fascia lata.
Fast-moving bimorph actuator based on electrochemically treated millimeter-long carbon nanotube electrodes and ionic liquid gel.
