In booth 301a/hall 3 at this year’s European Wound Management Association (EWMA) conference, scheduled to take place May 23-25, in Paris, France, Covestro will showcase material developments related to wearable smart patches and wound care. Wearable patch sensors (smart patches) are rising in popularity, as they offer a wide range of options for medical diagnosis. Current trends include enhanced convenience, even more functions, and ongoing miniaturization. In addition, the public is demanding more sustainable solutions and a move away from disposable products.

Together with its partner accensors, Covestro reports that it has developed a smart patch consisting of two elements: a disposable patch, which contains the sensors; and the ReUse patch, which contains the electronics. This makes it possible to reuse the electronic parts.

The production of wound dressings and plasters, as well as medical wearables, involves a multi-stage process. Covestro reports that the combination of a polypropylene (PP) backing with blown films from its Platilon® range made of thermoplastic polyurethane (TPU), in particular, is proving to be well-suited to satisfying today’s high demands for process efficiency and ease of use in wound care. In comparison to the production of paper backings, the generation of dust in the production process is significantly reduced.
