Discussion Overview

The discussion revolves around the concept of substances that can be manipulated using electric currents, exploring both theoretical and practical implications. Participants consider various materials and their properties, as well as potential applications in engineering and design.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant inquires about the existence of substances that can be manipulated with electric currents, expressing uncertainty about their knowledge in the field.
  • Another participant questions the extent to which "cause and effect" can be stretched in this context.
  • A suggestion is made to consider arc welding as an example of manipulating materials with electricity.
  • There is a claim that very few substances cannot be made to move with electric currents, but constraints are necessary for a meaningful discussion.
  • A participant mentions the design of a flexible RC (remote-controlled) device that requires specific properties, including the ability to return to shape after deformation.
  • Piezoelectric materials are introduced as examples that deform under voltage, although the movements are typically very small.
  • Another participant references fictional myomer muscles from the Battlemech universe, noting that current technology does not yet achieve the level of contraction and expansion depicted in that context.
  • There is a philosophical exchange about the distinction between what is possible versus what is probable in the realm of electric manipulation of materials.

Areas of Agreement / Disagreement

Participants express a range of views on the topic, with no clear consensus on the feasibility or existence of such manipulatable substances. Some ideas are speculative and others are grounded in current technology, leading to ongoing debate.

Contextual Notes

Participants have not fully defined the constraints or specific properties of the materials in question, leaving some assumptions unaddressed. The discussion also touches on both theoretical and practical aspects without resolving the technical challenges involved.

Please excuse my ignorance, (I'm not actually suppossed to be here, I'm a ME) but is there some sort of substance that can be manipulated with an electric current? (or some way I can make some?

How far are you willing to stretch "cause and effect?"

Again, excuse my ignorance but please explain (the movement can be broad and slightly ambigous if that's what you mean).
 
Consider an arc welder ...
 
so there is no substance I can make move with an electric current?
 
No ... there are few substances that can't be made to move ... the OP needs constraints ... many constraints.

You have in mind a material. This material will serve a purpose that only you know. One property is manipulable by electricity. Another property is? Can you divulge the purpose or will you have to kill us?

I know absolutely nothing about anything in chemistry, anyway I am trying to design a RC Kirby that is very (vey) flexible and needs to be able to be skooshed and still pop back up. But I'm trying to get the RC part down.

What exactly is that one propetry? :oldconfused:

Piezoelectric materials will deform when a voltage is applied. The change in size is typically very small, making it useful for very precisely controlling micro- and nanometer-scale movements.

interesting...very interesting :cool:

This brings to mind the myomer muscles used to move the walking tanks of the Battlemech universe. These artificial muscles contract when a current runs through them, providing the motive force to move anything from replacement limbs for amputees to the massive, multi-ton war machines that the universe is known for. Is this the sort of idea you had in mind? If so, we simply don't have that kind of technology at this time. Not that I'm aware of at least. Current materials only barely contract/expand when a current or voltage is applied.

Maybe. Maybe not.
