1. A feedback device for a structure, the device including:
- electrically conductive fabric for establishing an electrical current path with an electrical impedance, such that mechanical input to the device causes a change to the electrical impedance;
a voltage source to cause current to flow along the current path; and
a sensor for detecting change in the electrical impedance of the current path and producing a feedback indication when mechanical input to the device occurs.

Abstract
A feedback device for detecting a mechanical input and providing a feedback indication. For example, a wearable biomechanical feedback device that has an electrically conductive fabric sensor that can be closely fitted to a limb. Movement of the limb causes strain on the fabric sensor which alters its electrical impedance and triggers the feedback indication.

41. A method for producing a feedback indication in response to a mechanical input to a structure, the method including:
-
attaching electrically conductive fabric to the structure, the fabric having an electrical current path position on the structure such that mechanical input to the structure causes the electrical impedance associated with the current path to change;
applying a voltage across the current path; and
using a sensor for detecting the change in the impedance and producing a feedback indication. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56)
