TL;DR: In this paper, the macroscopic electrical field distribution is determined using capacitance-voltage and Kelvin probe techniques, and charge collection properties are then accessible relying on the relative weight that diffusion and drift have as carrier transport driven forces.

Materials and devices for transparent stretchable electronics
TL;DR: The development of transparent and stretchable (TS) electronics can enable a plethora of new applications such as TS integrated circuits, displays and sensors where high levels of both optical transparency and stretchability are required for conformal placement of devices on the human body or any arbitrary surface as discussed by the authors.
