Abstract
Stretchable biosensors are emerging tools to monitor patients. Previous research results should be compared and classified to offer satisfactory solutions to challenges facing the ideation and development of stretchable biosensors. At the same time, human body protein detection is of great importance because of being the most significant biomarker in patient health monitoring. Therefore, a literature review was conducted on flexible electronics to cover target biomarkers, measurement mechanism of affinity flexible biosensors, sensor fabrication materials, sensor fabrication procedures, and environmental effects on sensor performance. The challenges facing the development of wearable tattoo biosensors were also identified. According to the results, affinity flexible biosensors can perform wearable health monitoring of chronic patients in the near future; however, there is a wide research gap between affinity and stretchable biosensors.
