Perovskite ceramics and single crystals are commonly hard brittle due to their small maximum elastic strain. Here, large-scale BaTi0.95 Co0.05 O3 (BTCO) film with a SrRuO3 (SRO) buffered layer on 10 µm thick mica substrate is flexible bending radius of 1.4 mm semitransparent for visible light at wavelengths 500-800 nm. Mica/SRO/BTCO/Au cells show bipolar resistive switching the high/low resistance ratio up 50. The resistive-switching properties no obvious changes after 2.2 memory being written/erased 360 000 cycles nor bent 3 times. Most importantly, works properly 25-180 °C or annealed 500 °C. transparent oxide has good prospects application in smart wearable devices display screens.
