Flexinol Demo

Here is a really good simple sampling of the possibilities for exaggerating the slight movement of muscle wire: http://www.mrsec.wisc.edu/Edetc/cineplex/OHP_NiTi/index.html The example shown on the website uses Flexino NiTi memory wire available at Dynalloy, Inc.

NiTi actuator wires contract like muscle fiber when electrically driven. Batteries resistively heat the wire, causing it to shorten while exerting considerable force. NiTi can be incorporated into devices that are smaller, lighter, and easier to use than motors or solenoids. This demonstration shows some basic ways actuator wires may be used.

This FLEXINOL NiTi memory metal overhead projector demonstration is based on materials in the Sample Kit available from Dynalloy, Inc. The description provided here is adapted from the accompanying Dynalloy documentation. The overhead projector demonstration was developed by Eric J. Voss.
