Any type of material that expands with electricity?

AI Thread Summary
The discussion centers on the search for materials that expand in response to electricity. Participants mention "memory metals" and piezoelectric materials, such as quartz, which can exhibit expansion but typically do not expand significantly when current is applied. The conversation highlights that while piezoelectric materials can convert electrical energy into mechanical displacement, the degree of expansion is minimal. An alternative method discussed involves using a magnet and coil system, as seen in speakers, to achieve displacement. However, the original inquiry specifically seeks a liquid that expands with electricity, which remains unanswered in the discussion.

Is there any type of liquid or solid, or any material that will expand with the addition of electricity, or vice versa?

Welcome to the PF.

Have you looked at "memory metals" http://en.wikipedia.org/wiki/Shape-memory_alloy

.
 
piezoelectric materials. even quartz has this property and its used in crystal oscillators for electronic applications.
 
I have read about the smart metals but I was looking for something that does not need to be heated.

and for the quartz how much does it actually expand when the current is applied?

Not much: http://en.wikipedia.org/wiki/Piezoelectricity#Actuators

If you want some real expansion/displacement, how about using a magnet and a coil? That is how speakers turn electric current into displacement...
 
Yea but I was really looking for some type of liquid.

Know of any?
 

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...

Thread 'Resists for etching Aluminium with NaOH'

I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
