Does some material/metal exist that can be stretched and still transfer current?
For example: Say I have a rectangular item made of some metal or material(unknown to me at the time). On both ends, I have two small sensors attached. These sensors do nothing but want to establish communication between each other. For the purpose of this question, let's refer to them as sensor A and sensor B. Sensor A sends a message to Sensor B. Since the metal is not very stretched, it manages to transfer the message in electrical current to Sensor B in an elapsed time of .1 second.
Now, imagine that we stretch the metal a bit more, where its width is lowered and its length is increased. Since the message now has to travel further, I would expect the delivery to be greater than .1 second.
Note: Numbers used are just an example.
What sort of material or metal can I use to pass current, that when stretched, would alter the total distance a current would have to travel?
- Ideally, the two sensors will at the minimum be separated by 3-4 inches, and the metal/material would only stretch up to 1 inch.
