Octopus sucker-inspired patch delivers drugs into the body without needles or pills

Scientists have developed a new device inspired by octopus suckers that can deliver drugs without requiring needles or pills. They've already tested it in humans in a small, short trial.
The 0.4 by 0.2 inch (1.1 by 0.6 centimeters) patch can stick to the inner lining of the cheek, stretch across it and increase the absorption of an attached drug.
