Porcupine Quills Inspire Improved Medical Devices
Anyone unfortunate enough to encounter a porcupine’s quills knows that once they go in, they are extremely difficult to remove. Researchers at MIT and Brigham and Women’s Hospital now hope to exploit the porcupine quill’s unique properties to develop new types of adhesives, needles and other medical devices.
In a new study, the researchers characterized, for the first time, the forces needed for quills to enter and exit the skin. They also created artificial devices with the same mechanical features as the quills, raising the possibility of designing less-painful needles, or adhesives that can bind internal tissues more securely.
