Figure 5From: Electrostatic power generation using carbon-activated cotton thread on textile Simulated electric field properties between a CAT harvester and a PTFE sheet. Electric field between the CAT harvester (circled dot) and the PTFE sheet (curved line) when the gaps between them with a potential of −60.9 V are (a) 2 cm and (b) 2 mm, respectively. Unit is V m−1.Back to article page
