Fig. 5: The effect of varying line widths and patterns on the performance of liquid metal strain sensors (LMSS).
From: Precision aerosol-jet micropatterning of liquid metal for high-performance flexible strain sensors
a Optical images of LMSS with different line widths printed using aerosol jet printing (AJP) (scale bar: 5 mm). The experiment was repeated independently three times with similar results. b Sensing response curves of straight LMSS with varying line widths. c Influence of line width on the effective sensing strain of LMSS. d Optical images of AJP-printed LMSS with different patterns, featuring a minimum line width (min Lw) of 60 μm (scale bar: 5 mm). The experiment was repeated independently three times with similar results. e Sensing response curves of LMSS with five basic shapes, with insets showing magnified views. f The influence of patterns on the effective sensing strain of LMSS. Composite patterns: g l-sinusoid, h s-sinusoid, and i cross-grid, compared with the response curves of their corresponding basic shapes, with insets showing magnified views. Source data are provided as a Source data file.
