Bluestone Global Tech released a new video showing a test of their Gratom-O product (a graphene film on PET). This flexible film's physical integrity and high conductivity remain completely in tact, even after 25,000 bending cycles:

Gratam-O is a large-area CVD graphene film on PET (it can also be transferred to customized substrates). It features low sheet resistance and high optical transmittance (over 97%).
