Research on Flexible Sensors for Wearable Devices: A Review

With the development of new materials and the trend of miniaturization of smart devices, wearable devices are playing an increasingly important role in people's lives and occupying a larger market share. Meanwhile, the operation of wearable devices is based on the flexible sensors inside them. Although the development of flexible sensors has been very rapid in the more than 20 years since entering the 21st century, facing the booming market and demand at present, the development of flexible sensors still faces many challenges. For example: miniaturization, integration, sustainability, high precision and energy saving. This paper aims to summarize the development of flexible sensors, look forward to the future development of such devices and provides a reference for researchers.
