Washable Battery Makes Its Debut

In the rapidly expanding market of wearable electronics, a significant breakthrough has been made with the development of stretchable, washable batteries. These innovative devices, designed for smart textiles, have been developed by researchers at the University of British Columbia (UBC) and the Fraunhofer Institute.

The washable battery consists of several ultrathin layers of rubber-like polymers, encased within a protective polymer housing. This design allows the battery to be bent and stretched, making it suitable for a variety of wearable electronics, from watches to intelligent patches, and of course, smart textiles.

The materials used in the washable battery are incredibly cheap, ensuring affordability if produced in large quantities. This cost-effectiveness, combined with its remarkable runtime, makes it an attractive proposition for the industry. In fact, industry partners have shown a keen interest in the washable battery.

The washable battery is particularly interesting for future applications in smart textiles, particularly in medicine as carriers of biosensors. Its small size and durability make it ideal for use in practical, comfortable, and durable smart clothing.

Interestingly, the battery is made from zinc-manganese dioxide, a safer alternative to lithium-ion batteries for devices worn directly on the skin. The battery has undergone rigorous testing, surviving 39 wash cycles without losing functionality. It has been put through practical testing in both private and commercial washing machines.

The development of the washable battery is just one example of ongoing research in the field of battery technology. Other areas of focus include ultra-fast charging batteries and batteries made from trees. The researchers behind the washable battery are already looking to further increase its performance and lifespan.

In Europe, battery recycling is becoming a leading market, reflecting a growing emphasis on sustainability and the circular economy. As the wearable electronics market continues to grow, so too will the demand for innovative, sustainable battery technology like the washable battery.

Nicole Lücke, a science journalist specialising in energy, technology, sustainability, and medicine/medical technology, has been following the developments in this field closely. Her insights provide a compelling perspective on the potential impact of the washable battery on the future of wearable electronics and smart textiles.
