A group of researchers has made a breakthrough in the field of wearable technology by creating a new type of fabric that can generate electricity from the movements of the human body.
This innovation is based on the use of special molecules — amphiphiles, which both reduce friction and contribute to the generation of an electric charge.
Amphiphiles are already widely used in consumer products, such as diapers, to prevent skin irritation. Scientists decided to use them to create a fabric that would not only be comfortable, but also capable of generating energy.
«We wanted to create a material that would be pleasant to the touch and at the same time generate electricity», — says Saad Khan, one of the authors of the study.
The researchers found that some amphiphiles have special electronic properties that allow them to donate electrons. Incorporating these molecules into fabrics allows them to generate an electrical charge when rubbed against skin or other materials.
«Static energy harvesting technology already exists, but until now there have been no devices that could be worn for long periods of time, — notes Lilian Xiao, co-author of the study. — Our fabric is not only comfortable, but it can generate up to 300 volts, which is impressive for a small piece of material».
This discovery opens up new possibilities for creating self-charging gadgets: smart watches, fitness trackers, and even implantable medical devices. In addition, such a fabric can be used to create smart clothing that will be able to monitor a person's physical condition and respond to their needs.
«We are interested in finding new applications for these materials, — says Khan. — Perhaps they could be used in existing tactile devices or create new types of sensors».
This research is a significant step forward in the realm of wearable technology and could lead to more convenient and functional devices of the future.
