Artificial muscle is a generic term used for materials or devices that can reversibly contract, expand, or rotate within one component due to an external stimulus (such as voltage, current, pressure or temperature).The three basic actuation responses – contraction, expansion, and rotation – can be combined together within a single component to produce other types of motions
Hi Majid,
the man mechanism controlling muscle contraction is voltage, nevertheless in response to electrical stimuli (nerves) is the Calcium evoking muscle contraction, infact often is possible to obtain contracting artifical muscle in culture media for the presence of Ca++ ions.An other important trigger for contraction is chemical, likewise acetylcholine, but as previously mentioned, again acting on Ca++ fluxes.
Good luck
Hi,
I'm using the both types of pneumatic muscle actuator (contraction and extension). The both types of PMA are activated by air pressure and they produce force according to the direction of the movement. The bending behaviour could be occur by modified the structure of the single actuator, or by connect at least two actuators in parallel.
I have published four papers on design and model such type of artificial muscles, you can have a look to two of them in my profile. And there are a lot in google scholar.
Good Luck
