DNA polymerases in Biotechnology

Faster-replicating mutant polymerases are expected to provide robust performance with “fast” PCR instruments and cycling conditions. Moreover, identifying ...

The term „fast cycling performing" does not describe what the applications require and the piezoelectric actuator provide. There is no cycling, but motions, actions and reactions of the actuated lever arm in order to damp the amplitude of heartbeats.

Cardiac surgery, or cardiovascular surgery, is surgery on the heart or great vessels performed by cardiac surgeons.

Modern beating-heart surgery
In the early 1990s, surgeons began to perform off-pump coronary artery bypass, done without cardiopulmonary bypass. In these operations, the heart continues beating during surgery, but is stabilized to provide an almost still work area in which to connect a conduit vessel that bypasses a blockage

Now to the piezoelectric actuator:

A PVDF exhibits piezoelectricity several times greater than quartz. The piezo-response observed from PVDF is about 20–30 pC/N. That is an order of 5–50 times less than that of piezoelectric ceramic lead zirconate titanate (PZT)
:
For many sensing techniques, the sensor can act as both a sensor and an actuator—often the term transducer is preferred when the device acts in this dual capacity, but most piezo devices have this property of reversibility whether it is used or not.

As very high electric fields correspond to only tiny changes in the width of the crystal, this width can be changed with better-than-µm precision, making piezo crystals the most important tool for positioning objects with extreme accuracy—thus their use in actuators. Multilayer ceramics, using layers thinner than 100 µm, allow reaching high electric fields with voltage lower than 150 V. These ceramics are used within two kinds of actuators: direct piezo actuators and Amplified piezoelectric actuators. While direct actuator's stroke is generally lower than 100 µm, amplified piezo actuators can reach millimeter strokes.

Amplified piezoelectric actuators are specific actuators using piezoelectric materials as active material and have a specific design to overcome traditional limitations of classical direct piezoelectric actuators,[1] the limited stroke. As classical piezoelectric materials have a strain of 0.1%, it is practically impossible to reach significant stroke without displacement amplification (1 mm displacement would require 1 meter of piezoelectric material). The solution to reach middle range stroke is to use an amplification system.

Single-cell actuator
The principle is based on the deformation of an elliptic shell to amplify the ceramic strain. The ceramic stack is aligned with the great axis of the ellipse. A small deformation of the great axis creates a large displacement of the small axis. The amplification ratio can typically reach 20 times, that means such actuators can reach strokes of 1 mm.
:
Lever arm amplification
Another method of amplifying the piezo stroke is to use a lever arm, which can be a primary or a secondary amplification mechanism, and can be used to generate displacements with 10 to 40 times magnification.

(Note: the shown piezoelectric actuator looks like these devices.)

To meet the requirements of Industry 4.0 control system, it is necessary to develop fast communication characterized by sensor to actuator latency of 1 ms (Fig. 5). The network than can enable such communication ist known as tactile internet. The term tactile internet is chosen since end to end speed of 1 ms corresponds to the reaction of human to sense, which has the shortest reaction time of all human senses.

Furthermore, the exact compensation of a known and constant actuator latency leads to a delay between the real and the desired tracking of the controlled variable
:
In order to evaluate the quality of the system, frequently the average response time (latency) and its jitter is considered.

With this the phrase part can be improved:

XXX are assistant/serviceable/performant and respond quickly if used for YYY
=>
XXX sont efficaces/opérationnelles/performantes et répondent rapidement si elles sont utilisées pour YYY
