do u have any idea about any low voltage(5v) devices which can give a mechanical output when voltage is applied(like solenoid):smile:
 

Depends on the intended mechanical action (force, travel and speed): motor, piezo actuator with boost converter, thermal (bimetal) actuator, electrochemical (electrolytic) actuator.
 

thats good,
but the size(~10*15mm) and power loss of the actuator is also constrianed.here i need is the mechanical force to push.can u give me more ideas
 

A very small motor attached to a fine-thread machine-screw can drive a nut along.

Of course, it gets a bit harder, because you must worry about end-stop switches and stalling the motor. You may need two nuts fastened together and a rider between them or vice-versa.
 

servo motor should do the trick.
 

ya thats great,

using servo motor with threaded screws serves the purpose,but installing & operating the servo motor is harder and costlier than the earlier used solenoid.
can u suggest me some ideas which is simple and low cost:).
 

To sort out the confusions relating to my question,iam clearly mentioning my need.

I am in need of a device(other than solenoid and bimetal) which will give mechanical output when electrical supply is given...
constraints relating to it are
-it should be operable on 5v-12v dc
-it size can range from(5*10mm) to (10*15mm)
-its mechanical output force > 70 gm
-its speed > 1m/sec
-travel distance 3-3.5mm
-it must be easily realisable,considerable cost


help me.............plz
