Finding a way to thrive in the Earth’s ever-evolving environment and rapidly changing climate requires radical thought, innovative application and sustainable solutions. Where others might see disaster and dystopia, the truly transformative mind – that of biomimicry designer Jun Kamei, for example – manifests opportunity, challenge and adventure.  

With the world’s temperature predicted to increase 3.2℃ by the year 2100 (according to a report by The Intergovernmental Panel on Climate Change), causing a sea level rise that would affect billions of people and submerge some coastal cities altogether, Kamei is thinking not of flood but an amphibious future: ‘A time where large percentages of the planet’s population will spend as much time in the water as on the land,’ he says.

With the help of Kamei’s revolutionary gill garment – a vest and accompanying mask intended to facilitate underwater breathing for humans – a recreational dive to a neighbouring church, a night swim through submerged streets or even a sub-aqua commute from home to work may be possible.

Developed by London’s Royal College of Art, in collaboration with the RCA-IIS Tokyo Design Lab, Amphibio is a 3D-printed, amphibious garment made from a specially developed material that supports underwater breathing by replenishing oxygen from the surrounding water and dissipating the carbon dioxide that accumulates in the system.  

‘The technology for Amphibio was inspired by diving insects surviving underwater by virtue of a thin layer of air trapped on their superhydrophobic skin surface, which works as a gas exchanging gill,’ explains the designer. ‘Using 3D-printing technology, our newly developed material can be shaped in complex forms to do the same thing.’

It’s a big idea to help solve a major problem but Kamei is not fazed by the ambitious enormity of the task ahead. ‘I feel that designers should not be scared of tackling the bigger problems,’ he says. While the design community tends to operate at ‘product level’, his kind of micro design thinking can actually prove pivotal in tackling the macro and complex issues around climate change and seismic environmental shifts.

‘I would urge people wanting to take action on climate change challenges to be informed of the actual science,’ says Kamei. ‘Any ideas must always consider the science first.’

With his invention still in the prototype stage, Kamei’s next action is testing Amphibio to support underwater breathing. ‘If you are familiar with free-diving and scuba-diving equipment, Amphibio sits right in between those two,’ he says. ‘Our membrane technology enables the material itself to collect oxygen dissolved into seawater. In the near future, the wearer would stay underwater for longer, but with far less equipment (such as heavy oxygen tanks) than you need for conventional scuba diving.’

Adapting the concept for sustainable sportswear

This kind of future-facing research and design has produced some exciting applications for the wider present – the discovery that Amphibio’s membrane technology is also suited for the manufacture of waterproof, breathable sportswear textiles for everyday use on dry land.  

‘The principle is really simple,’ says Kamei, ‘a combination of material science, and modern technology. Our Amphitex material is waterproof, but the membrane’s micro pores allow gases to pass through it. Which means that oxygen is able to travel from the water to the inside without actually letting any water pass.’ And unlike many of its sporting and impermeable competitors currently on the market, Amphitex – which is free from PTFE (polytetrafluoroethylene) and is made from a single-source (or mono) material, making it 100 per cent recyclable – is truly sustainable.

Both projects, Kamei says, are hard-wired to a sustainable future, ‘in the sense that everything we do is to mitigate the impact of climate change. It's definitely important to have a multidisciplinary eye when you tackle sustainability challenges. By trying something radically conceptual, future-oriented and different, we ended up creating Amphitex. You start with one idea and then another door opens and that leads to another door. In material science, things have a tendency to morph like this – you invent something and then you realise that it might have an application in places that you’ve never thought about before.’ 

Being chosen as a Change Maker is an honour, says Kamei, ‘but it also comes with responsibility. It’s now very important for me to deliver on what I promised to do and bring positive results for the environment.’
