“Energy Ink”, the self-recharging battery that generates electricity from moisture

According to some researchers, half of the solar energy that bathes the Earth in heat goes to a single process: the evaporation of the water that covers about 71% of our planet. Now Australian company Strategic Elements wants to harvest that energy and is working with the University of New South Wales and CSIRO to develop flexible, self-charging battery technology that harvests electrical energy from moisture in the air to directly supply appliances. to plug them in.

Electrical load capacity has been increased from the milliamp-hour range to the amp-hour range. Strategic Elements has dubbed this technology “Energy Ink”, claims that it is non-flammable and is created with safe, environmentally friendly and sustainable materials, and that can be printed on soft plastic.

One of the markets it addresses is that of battery powered fitness equipment. The human body produces a lot of moisture throughout the day, as you may have seen, especially when exercising.

The company says this moisture-powered technology is already producing more than enough energy to operate.”most existing devices in the massive $10 billion electronic skin patch market“, and that he hopes to have a working prototype in the third quarter of this year to prove that he can do the job, power devices that never need to be put on a charger other than your own sweaty skin.

Strategic Elements doesn’t give much detail, except that uses graphene oxide and that it is developed in collaboration with UNSW and CSIRO.

So yeah, while we don’t know how close this research is to the Energy Ink product, it seems the company’s promises are within the bounds of what’s possible, and depending on how this gear interacts with human skin and sweat. , a line of “Powered by Moisture” wearable electronics could start appearing in the next few years.

Strategic Elements claims that their amp-hour humidity battery is approximately 36 cm2. He will try to make a 100cm square test unit in a few months, and says UNSW has a printer capable of producing up to a 3m2 matrix.

Not so long ago, many said that it was impossible to produce usable energy from moisture. For us, the fact that we are now realistic about producing electrical energy in the ampere-hour range solely from the humidity of the air is a great achievement. Our technology does not rely on rare materials and does not involve security risks, and can also bring flexibility to electronics.

There is an obvious near-term target market for electronic skin patches, but we’re also excited to be clearly in the early stages of testing the fundamental upper limits of this technology. The current success is a testament to the close relationship developed between the company, Professor Dewei Chu and his team at UNSW, built over years of collaboration in e-ink development.
