Recent advances of flexible sensors for biomedical applications

Ultrathin, soft, flexible and stretchable sensors offer good opportunity to design personal health diagnosis and treatment systems by fabricating wearable biomedical devices for continuous health monitoring and preventive medicine. This paper summarizes the recent advances of flexible sensors for next generation biomedical applications. Materials used for flexible sensors are first briefly introduced. Followed to this part, the latest developments of flexible sensors for biomedical applications are discussed in detail, including flexible sensors for skin-attached devices and implantable devices. Finally, the challenges and future research directions of flexible sensors are also discussed in the development of biomedical devices.
