Executive Summary
Bubble energy could be used to deliver drugs in a more reliable way than mechanical methods, according to researchers at Johns Hopkins University in Baltimore. Mechanical engineering professor Andrea Prosperetti and his team have developed a pump with no moving parts in which a bubble, created by electrically heating saline in a series of tubes, pushes the liquid ahead of it as it expands. The process is repeated as long as the current is maintained, providing precise drug delivery. The device could potentially be small enough to be implanted.
