Is there any material that can harden when electricity is passed through it and soften when current is stopped?
I basically want to use this material in a glove. The glove should get tough and difficult to bend when I pass electric or magnetic field through it. And once the field is removed, it should get back to how a normal glove works.
The best options to be used seem to be the Electrorheological or the Magnetorheological fluids but there seems to be a problem for both- 1) Which fluid can I use for Electrorheological application. Can it be made at home via some chemical or physical reaction? 2) If I use a mixture of Iron fillings and vegetable oil as a magnetorheological fluid, how do I create a magnetic field using arduino?
