  1. PDMS polydimethylsiloxane, PEDOT poly(3,4-ethylenedioxythiophene), PSS poly(styrenesulfonate), P3HT regioregular poly(3-hexylthiophene-2,5-diyl), PC60BM [6,6]-phenyl-C61-butyric acid methyl ester, Ti titanium, TiN titanium nitride.
  2. List of parameters used for the construction of the deformable shell. Apart from PDMS, the behaviours of the other materials were considered isotropic elastic. The values for Young’s modulus and Poisson’s ratio of the used materials and the hyperelastic coefficients for PDMS were taken from the following references80,81,82,83,84,85,86.
