Extended Data Fig. 2: Finite element analysis of strain distribution on actuator layers.
From: A filamentary soft robotic probe for multimodal in utero monitoring of fetal health
(a) Overall strain distribution. (b) Strain distribution on the outer outer tear-resistant platinum-cure silicone elastomer (for example, DragonSkin-type, Smooth-On, Inc) layer. (c) Strain distribution on the low-modulus platinum-cure silicone (for example, Ecoflex-type, Smooth-On, Inc) chamber with enlarged views of critical edge leading to failure. (d) Strain distribution on polyimide strain limiting patterns. (e) Strain distribution on the copper layer of the probe.
