stretchable

No longer is it dogma that the stiffer a polymeric material is, the less stretchable it has to be.

The patch is made of a silicone elastomer that houses an array of small piezoelectric transducers sandwiched between stretchable copper electrodes.

"Because while we understand what makes them hard and stretchable, we can only speculate about what makes them so sticky."

The team optimized the actuator structure to allow both expansion and contraction, combining it with CLCEs, and developed a highly adaptable stretchable device.

The rest of the layers consist of stretchable electrodes.
