Towards wearable electronic devices: A high linearity bionic flexible stretchable sensor based on MXene/GO...

Flexible stretchable sensors have a wide range of applications in fields such as health monitoring and human-computer interaction. However, developing stretchable sensors that combine high sensitivity with linearity remains a significant challenge. Here, we are inspired by spider crack bionics and adopt gradient stiffness design, and successfully prepare flexible stretchable sensors with excellent performance based on MXene/graphene oxide nanocomposites. The sensor achieves a sensitivity of 51.36, a linearity of 0.999, a fast response time of 60 ms, and a strain detection lower limit of 0.1 %. The study demonstrates the successful application of stretchable sensors for monitoring human movement, recognizing handwriting, and interpreting sign language. Therefore, the flexible stretchable sensor proposed in this study holds great promise for human motion detection, wearable electronics, and human-computer interaction.
