Characterizations of LM circuits. a The microscopic image showing the cross-section of LM circuits on the PDMS substrate. b Demonstration experiments on the stability of printed LM soft circuits when experienced different deformation forms: folded, stretched, and bended. c The images of the LM stamp and fabricated LM circuits with the different widths. d Characterization of LM circuits by two methods on three different substrates (Ecoflex, PDMS and PVA-H)
