People with disabilities who require powered mobility assistance currently have no choice other than electric devices with expensive, slow-charging batteries. These devices are also incapable of being exposed to wet environments due to the electronics used to drive them. As a result, users are restricted from participating in water activities – such as going to a pool, waterpark, or beach – and users must transfer out of the device when it’s time to take a shower. The PneuMobility devices are driven using only compressed air, which removes the need for electronics. Without batteries on board, our devices weigh a fraction of electric powered devices, recharge in minutes, and no longer require expensive battery replacement. Not only could that save the user up to $500 per year, but it also removes the hassle of proper battery disposal.
