11.   The device uses spongy artificial muscles to unleash drugs into the body.

12.   The devicewas among a host of new robotic technologies, including artificial muscles and robotic Legos, which SRI International in Menlo Park showed off yesterday.

13.   The institute is charged with manufacturing a uniform that can repel bullets, protect against chemical and biological agents and even provide artificial muscles to its wearers.

14.   The new device, developed by American scientists, uses spongy artificial muscles to release variable amounts of medication.

15.   The U.S. Navy is developing stealth submarines that have exchanged propellers for artificial muscles that let them slip silently through the water like a fish.

16.   The unusual property of shrinking when heated and expanding when cooled makes SMAs ideal for artificial muscles.

17.   They have exchanged noisy propellers for quieter artificial muscles which leave less visible wakes.

18.   Professor Pierre Rabischong of Montpellier University in France, a project coordinator, said the implanted chip allows Merger to create artificial muscle movement.

19.   The artificial muscle is the brainchild of Mohsen Shahinpoor and colleagues at the University of New Mexico at Albuquerque, says the British weekly magazine New Scientist.
