a Photographic images of the W/PLGA with 30 s (left), 45 s (middle), and 75 s (right) of electrospinning time (Aperture F 5.6 and ISO 1600). b SEM images of W nanomesh transferred on PLGA substrate (left). Magnified view of an interconnected junction in W nanomesh (right). c Transmittance spectra from 300 to 700 nm wavelength and (d) correlation between sheet resistance and optical transmission at 550 nm wavelength of the W/PLGAs with different electrospinning times (A, 30 s ; B, 45 s ; C, 75 s) (n = 4). e Photographic images of the LED operation connected to W/PLGA bent on an artificial hand with external voltage 3 V (Aperture F 4.0 and ISO 6400).
