TABLE I.

The moduli of elasticity of the physiological and silicone VF models for each layer. Smooth-On Ecoflex 0030 and Dragon Skin 10 silicone mixtures (Smooth-On Inc, Macungie, PA) are denoted by EF and DS, respectively.

Layer	Physiological range (kPa)	Silicone VF model (kPa)	Silicone ratio (Type of silicone)
Adipose tissue	1–10 (Ref. 67)	4.04	1:1:4 (EF)
Body	1.5–50 (Refs. 68, 70, 72)	7.13	1:1:2 (EF)
Cover	1–8 (Refs. 65, 69, 71, 73, 74)	1.10	1:1:7 (EF)
Epithelium	$\text{Not}\hspace{0.17em}\hspace{0.17em}\text{measured}$	81.10	1:1:1 (DS)
