Scotch tape finds new use as grasping 'smart material'

#Scotch tape, a versatile #household #staple and a mainstay of #holiday gift-wrapping, may have a new #scientific #application as a #shape-changing "smart material."

#Researchers used a laser to form slender half-centimeter-long fingers out of the tape. When exposed to #water, the four wispy fingers morph into a tiny #robotic #claw that captures water droplets.

The #innovation could be used to collect #water samples for #environmental testing, said Babak Ziaie, a Purdue University professor of electrical and computer engineering and #biomedical #engineering.
