Summary: | The invention relates to a flexible strain sensor with a substrate having an extremely low temperature effect, and the sensor comprises a metal composite flexible substrate which comprises alternately arranged polymers and metal microstructures; the strain sensitive grid resistor is arranged above the metal composite flexible substrate, and the grid direction of the strain sensitive grid resistor is consistent with the arrangement direction of the metal microstructures in the metal composite flexible substrate. The invention also relates to a preparation method of the flexible strain sensor with the substrate having the extremely low temperature effect. The strain direction detected by the flexible strain sensor is consistent with the low thermal expansion coefficient direction of the metal composite flexible substrate, and the thermal deformation rate of the metal composite flexible substrate in the direction is low, so that the influence of the substrate temperature effect on strain measurement in the strai |
