| Popis: | The application of a bistable magnetic microwire as a contactless sensor of strain in a beech plywood strip is tested. The results are compared to the strain gauge measurement. It is shown that the magnetic response of the microwire increases linearly within a low load range. At a higher load range, the response fluctuates, probably reflecting the local fluctuation of strain distribution. The sensitivity of the microwire’s response allows for the theoretical strain sensitivity down to 6 × 10−8. The small size of the microwire permits its application between plywood layers, making it a SMART material with self-monitoring of its stress. |
