Outline
Polymer-nanocomposite based flexible and stretchable strain sensors offer portability， simple sensing mechanism， and stable signals， attracting considerable attention in wearable electronics. This paper reviews the research progress of polymer-nanocomposite flexible stretchable strain sensors， with a focus on introducing common types of the properties of polymers and the types of sensing materials. The evaluation of sensing performance mainly includes sensing range and sensitivity. The main factors affecting sensing performance include the selection of polymer materials， the configuration of the conductive network， and the structure design. Although the construction of different types of structures， such as micro-cracks， pore structure， and wavy structure， can contribute to improving the stretchability and sensitivity of the sensor， it is still a challenge to balance its broad detection range and high sensitivity. The main advanced research trends of sensing performance improvements can be oriented towards the selection of highly elastic polymer materials， the optimization of conductive network configuration， and the design of new structures. Polymer-nanocomposite based flexible and stretchable strain sensors will have broad application prospects in human motion detection， personal health monitoring， phonation monitoring， medical monitoring， and futuristic home design.
