A very useful electronic component that turns mechanical energy into electrical, uncle bumblefuck has found them in many things including: a hazard fraud digital torque meter, and pressure transducers. He has used one in his series on testing wrenches until they break where he connected it to the osmelloscope to graph how much torque it took to break the wrench.

Does not convert energy! Converts mechanical strain into change of electrical resistance so translates very small mechanical movement into something the angry pixies can understand.
