Soft, Stretchable and Sticky PDMS

• A tunable process of polydimethylsiloxane (PDMS) has been created with a tiny amount of a polyethylenimine, ethoxylated (PEIE) solution. With varying the PEIE fraction, the softness, stretchablility and stickiness of a commercial PDMS (Sylgard®184) are enhanced at the same time. We controlled the curing process of the tuned PDMS to achieve desired mechanical properties. A soft strain sensor for finger movement monitoring is successfully demonstrated with a liquid alloy resistor in the soft, stretchable and sticky (S3-PDMS) packaging.
