• electric motor
  • brakes
  • pneumatic (air)
  • hydraulic (water)
  • Shape memory alloy (metal, as lina described)
  • piezoelectric
  • piezoelectric pressure valve:


Heat dissipation and response time may be significant impediments.

Sample kits available through hobbyist sites.

By the meter, this stuff is rather cheap (£5 per meter, roughly)




Including numerous kits and a text: “Actuator Design Using Shape Memory Alloys”, as well as off the shelf integrated shape memory alloy actuators (20 cost 8000¢, or 100 cost 300 USD) These have 20 mm displacement, and one pound pull
