a, The ratio of the capacitance (C) after and before the fibre was bent with, from right to left, bending radii of 3.2, 2.0 and 1.2 cm for 1,000 cycles. To ensure a reliable bending radius, the fibre was mounted on a polymer substrate. After the first 1,000-cycle test, the fibre was successively subject to the second and the third 1,000-cycle tests. b, The ratio of the capacitance after and before the fibre was twisted with, from right to left, angles of 45°, 180° and 540° for 1,000 cycles. All tests were done successively.
