Touch Actuated Micropump for Transdermal Drug Delivery
Purdue University researchers have developed a new type of pump for drug-delivery patches that would use arrays of microneedles to deliver a wider range of medications possible than with conventional patches. The pump contains a liquid that boils at body temperature so that the heat from a finger's touch causes it to rapidly turn into a vapor, exerting enough pressure to dispense the drug through the microneedles. This technology's low-cost and battery-less operation make it the ideal single-use disposable transdermal drug dispenser.
