Researchers develop implantable device that can deliver a drug on its own, precisely when needed & at accurate dosage
Many drugs come with complicated dosing regimens, making it difficult for patients to keep track of when it is time to take the next pill. Those taking drugs for hypertension, rheumatism, and other conditions can have very personalized schedules that require accurate timing. Researchers at Houston Methodist hospital have now developed an implantable device that can deliver a drug on its own, precisely when needed, and at the accurate dosage.
Unlike most previous drug delivery implants, this new device has no pumps, valves, or even a power supply. It works thanks to a nanofluidic membrane through which a drug can be diffused by changing the electric field applied to it. The device can release a drug slowly and evenly, keeping its concentration at a certain level and avoiding unnecessary dips and falls that can result in complications.
Ilika plc (LON: IKA), a pioneer in solid-state battery technology, recently announced that it has increased the energy density of its thin film batteries by 10-fold since the launch of its first product, the Stereax® M250, by improvements made in Ilika’s processing methods. This makes Stereax® the most competitive, energy dense technology for miniature solid-state batteries used in IoT (Industrial sensors, Automotive, Smart Homes and Cities) and of course MedTech.
