Can flexible batteries revolutionise power in medical devices?
Ian Bolland asks EJ Shin, Jenax and Andy Baker, HP1 Technologies, about the effect flexible batteries could have on medical devices
This interview followed a webinar on how flexible batteries can be used in the manufacturing process, ‘creating product innovation breakthroughs with flexible power.’ It covered the importance of continuous innovation, changing the mindset of what batteries can do, and new standards of safety, flexibility and control.
According to MarketsandMarkets the flexible battery market is estimated to grow from $97 million in 2016 to $958 million by 2022, propelled by the miniaturisation of electronics devices, and the demand for wearables.
Shin notes that wearables can benefit from flexible batteries. There is also a use within clinical setting, allowing medical professionals to manoeuvre easily instead of carrying power banks.
Shin adds: “Flexible batteries can be an enabling technology for many devices and for many aspects in the medical field.”
So where is the opportunity within medical device design? Is the demand for flexible batteries being driven by device design, or are the batteries leading to more innovative designs?
“I would say it’s the synergy of both,” Shin explains. “Device makers want to make the device more flexible so flexible components are needed. We want to find a perfect or usable application that can be benefitted by flexible batteries.”
The batteries were also shown to have a life comparable to standard batteries, while also showing that when they have been cut through, there is no sign of leakage – a potential selling point when it comes to being used in a field when safety is imperative.
“Making the flexible battery is one technology and also making the entire battery safe is another. We combine the two. We have made it safe by developing semi-solid electrolytes and also years of testing and experience on production know-how.”
Last year Jenax, announced a breakthrough in battery safety with non-flammable liquid electrolytes. This aims to solve the problem of batteries that catch fire or explode in extremely hot temperatures or when short circuited. This technology can increase the safety of wearables.
Andy Baker, CEO – sport and leisure – HP1 Technologies, which builds printable graphene-based sensor systems, developed a helmet containing over 20 sensors on the surface.
Baker recently attended an NFL conference. The reduction in concussion in the sport is a key issue. The helmet requires sensors, so needs flexible batteries.
He explains that connectivity is a huge consideration but it’s possible to include flexible batteries in devices such as smart bandages; and suggests there is room for diversification as well as highlighting safety features.
“The main area for health is they do not explode when pierced or leak corrosive substances. Flexible batteries can be pierced and cut and will still supply power until replaced and will only leak a small amount of a polymer gel which is harmless and can be on the skin without causes any discomfort or burns.
“I think the main message is to think differently, if you think differently you can power differently.”
