Measure biological parameters and cure
What are active micro-needles?
Less invasive than traditional needles, micro-needles reach the deep layers of the epidermis to deliver drugs, measure physiological characteristics, or send light to specific wavelengths. CEA-Leti has developed and qualified a new technology of biocompatible polymer micro-needles, ranging in length from 250 μm to 3 mm. Directly applicable to the skin, multiple assembly can cover several square centimeters.
Several preclinical projects are underway to develop micro-needles devoted
to worn measurement, combining interstitial liquid collection with electrical,
electrochemical, or optical measurements. These systems will pave the way to
continuous monitoring of several metabolites involved in various pathologies.
Large-scale manufacturing processes are also being developed.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
