Abstract

The development of flexible photodetectors is believed to have great potential for future optoelectronic applications, such as biomedical imaging and smart wearable systems. Here the work proposes a simple and low-cost approach for integrating a flexible and wearable ZnO ultraviolet (UV) photodetector using polyester fabric as the platform for the first time. The ZnO nanowires coated polyester fabric was prepared by a low-temperature hydrothermal approach. They measured the performance of the photodetector in terms of I-V characteristics and time-resolved photocurrent. The results showed that the as-fabricated ZnO UV photodetector presented great reliability. Additionally, the working mechanism of the device was also discussed.
