Wear and Tear represents the abrasion of the material that happens naturally during the ageing and usage of the material. For better control of the Wear and Tear, sensors are used as they can warn the user in advance that the material/device can reach some critical limit when its next usage will damage the material/device itself or the production process. MicroWire as a miniature sensor of micro-dimensions represents a suitable choice for Wear & Tear monitoring, as it can be inserted inside of the material without additional wiring while providing information about W&T status.
