Researchers have just developed a battery that could launch a new era for connected clothing. Flexible and stretchable, it can also be washed in the washing machine without being damaged.
Their battery is based onand dioxide , usually used to create in a form . To make it flexible, they reduced them to powder and integrated into a biocompatible. They superimposed several thin layers, which they then wrapped with this same polymer. The result is a and stretchable.
A very affordable battery
The researchers then came up with the idea of checking that the battery was properly sealed by passing it through a washing machine. Their prototype underwent 39 cycles ofin domestic and industrial washing machines without degradation. They chose to create a zinc-manganese battery because these elements are much less toxic than . The battery should therefore not pose a problem if it breaks when worn next to the skin.
The choice of materials should also allow a very low production cost. The researchers hope that when their battery is ready to market, it will be produced at the same price as aclassic. It can then be integrated into , from worn directly on the skin or in .
