FaceBit mixes face masks with health gadget

All through the pandemic, we’ve seen a number of firms strive their hand at “good” face masks. Essentially the most helpful of the bunch might have simply been revealed not by an organization, however by engineers at Northwestern College. Dubbed “FaceBit” – the engineers behind this venture describe it as “Fitbit for the face” – this isn’t a full masks, however somewhat a sensor that may be magnetically hooked up to the N95 and surgical masks healthcare staff already put on.

Well being monitoring in your face masks

FaceBit is described in each the analysis article “FaceBit: Good Face Masks Platform” and in a information publish on the Northwestern College web site. Josiah Hester, PhD of the McCormick College of Engineering and Utilized Science, led the gadget’s growth.

Because the title suggests, FaceBit is all about monitoring numerous well being metrics. The sensors within the tiny board Hester and his group created can observe the guts fee and the respiration fee of the wearer via the masks it’s hooked up to. In that Northwestern College information publish, Hester explains that FaceBit is delicate sufficient to detect the in any other case imperceptible actions our faces make every time our hearts beat. With that in thoughts, it’s no marvel that FaceBit also can observe one thing extra evident like respiration fee.

That coronary heart and respiration fee information is then uploaded to a companion smartphone app, permitting customers to see their well being information, identical to in the event that they have been sporting a Fitbit. FaceBit additionally tracks the overall time customers have worn their masks, and might probably even give healthcare staff a window into when they need to take a break, as elevated respiration and coronary heart charges are sometimes related to elevated stress ranges.

FaceBit also can alert customers when the seal on the N95 masks they’re sporting might have been damaged. Whereas it will possibly’t immediately confirm if facial seals are nonetheless in place, it will possibly detect bumps that might be sturdy sufficient to interrupt them and alert the consumer that they could want to repair their masks. It will probably additionally inform when the masks turns into too free to make sure a correct match.

FaceBit has significantly lengthy battery life

Maybe probably the most spectacular half about FaceBit is its lengthy battery life. Whereas FaceBit comes outfitted with an onboard battery, the small dimension of the board limits simply how massive that battery might be. FaceBit can harvest small quantities of energy from daylight and even the consumer’s breath and movement, giving it a possible battery lifetime of 11 days.

That’s spectacular and in addition crucial. Within the video above, Hester explains he didn’t need to develop a masks that needed to be recharged each few hours. Eleven days of battery life exceeds that of most of the smartwatches we see right now, however then once more, the low-power elements on the board itself (together with the truth that it doesn’t have a show) assist make sure that customers can squeeze as a lot energy as attainable out of that tiny battery.

Northwestern College says sooner or later, we may see units like FaceBit which are powered totally by “harvested thermal and kinetic power.” Whereas Hester says that FaceBit nonetheless must undergo scientific trials, it feels like he and his group have created a succesful gadget right here. They’ve additionally launched it as an open-source venture so anybody can construct on the work the group has already achieved.
