It’s easy to see why wearable medical devices have become increasingly popular in recent years. These gadgets have been made to be worn on the body and offer a wide variety of advantages to the user. Wearables have enormous potential to transform the healthcare system, particularly in vitals monitoring and activity tracking. Materials that can intelligently and autonomously adapt to the wearer’s movements and changing environmental conditions are necessary for these devices to be truly effective. Polymers are helpful for this purpose.
Polymers are synthetic macromolecules characterized by long, repeating chains of monomers. They have many uses, ranging from plastics and textiles to medicine and electronics. Polymers’ versatility in responding to shifting environmental conditions makes them ideal for use in wearable technology. Some polymers, for instance, are well-suited for use in soft robotics and smart skin applications because their rigidity can be altered depending on environmental conditions.
Polymer materials with built-in switchability have recently been developed by scientists at the Universities of Stuttgart and Tubingen; these materials hold great promise for future wearable medical technology. These materials are extremely flexible because of their ability to adjust to their surroundings automatically. Even when subjected to large deformations, they can still undergo elastic changes that allow them to conform to the needs of the application at hand.
The researchers detail their methodology for creating these smart polymer materials in a paper published in Advanced Materials Technologies. As the wearer moves and the surrounding environment shifts, the material’s properties can change on their own. Due to their malleability, these materials have been dubbed “intelligent rubber materials” by the study’s authors.
These smart polymer materials have a wide range of possible applications in the medical field. For instance, they might be used to make soft exoskeletons that help stroke patients walk again. These tools would benefit from variable viscoelastic properties to accommodate fast and slow motion. Researchers at the Universities of Stuttgart and Tubingen have created intelligent polymer materials capable of doing just that, making them ideal for use in soft robotics.
These materials may also find use in the delivery of drugs through the skin in a controlled fashion. This material can be used as a patch for transdermal drug delivery due to its hydro-adaptability and reversible water absorption capacity. The researchers found that the patch itself regulated the release of the active ingredient in response to the varying moisture levels of the wound, allowing them to conduct experiments with the release of the painkiller diclofenac in a skin model.
In the future, researchers at the Universities of Stuttgart and Tubingen hope to look into multifunctional material systems that can both respond actively to triggers like electrical stimuli while also adapting on their own to their surroundings. Additionally, they intend to model and predict complex architectures with the help of simulations.
The university’s Data-Integrated Simulation Science (SimTech) cluster of excellence also benefits from the findings of the polymer materials research. Polymer research combined with data-integrated simulation science paves the way for next-generation wearable medical devices that can respond to patients’ needs in any setting.
In conclusion, intelligent polymer materials are an integral part of the future of wearable medical devices, which have the potential to alter the healthcare system radically. Researchers at the Universities of Stuttgart and Tubingen are paving the way for cutting-edge wearable medical devices by developing materials that can adapt autonomously to the wearer’s movements and changing environmental conditions. Everything from flexible exoskeletons to transdermal drug patches is within reach. These tools have the potential to revolutionize medical practice with more study and refinement.
