Gecko Adhesive

University of California, Berkeley, engineers have designed a gecko-foot mimicking adhesive that is very strong but easy to separate. 42 million tiny hard plastic microfibrils are found on a single square centimeter. It takes hold when it slides down a smooth surface, rather than being pressed against. Two square centimeters can hold .88 lbs. (News source.)

Tree Frog Tape

Indian researchers have created a new sticky tape based on the toepads of a treefrog. The tiny channel-filled patterns allow the tape to be unstuck and reused, while being up to 30 times stickier than conventional tape. (News source.)
