Electronic – Energy conversion from Electrical to Mechanical

actuatorenergymechanicalpower

I have a requirement where I have to design a very small device capable of pulling in and out a small piston through a feedback.
I know it can be done using motor but AFAIK I need higher voltage and current which is not possible through, in my case,a button cell rated 1.5 V.

Here I seek your suggestion, is there any other effective solution to convert electrical energy to mechanical energy.I thought about an electric spark to initiate some chemical reaction(like in automobile) but it was complete failure as I needed to generate high voltage.
Thanks for your help.

Look at piezo linear actuators. They work at relatively low energy rate, slow speed, low torgue, accurate movement in range of few mm. With correct driver the motor will consume very low power
