Synergistic Microcrack Engineering and Auxetic Metamaterials for Enhanced Sensitivity in Stretchable Strain Sensors

open access: yesAdvanced Materials Technologies, EarlyView.
A highly sensitive crack‐based piezoresistive strain sensor is developed using a biaxially pre‐stretched multi‐walled carbon nanotubes/Ecoflex composite and integrated with auxetic metamaterials. Biaxial pre‐stretching improves the sensitivity by 56% compared to the uniaxially pre‐stretched strain sensor.
