Today mechanical flexibility has become an important feature for electronic devices, especially in flat display panels. Here we demonstrate the device operation of a tungsten oxide-based flexible electrochromic transistor (ECT), which was fabricated on 0.1 mm thick polyethylene terephthalate film. The ECT can be operated by applying voltage of 3 V for 1 s when the radius of curvature was larger than 16 mm, indicating that the flexible ECT exhibited a strong resistance to static strains. However, the resistance of the channel increased by fatigues from applying cyclic flexural strains. Present flexible ECT would highly be useful for the economically viable curved display panels. However, its vulnerability to fatigue needs improvements for other applications.
