Among the many devices currently available to monitor or track physiological signals, the latest to join the list is interestingly a new smart pajama that can track these signals during the wearer of the pajama’s sleep. The pajama is being called Phyjama by its creators- a team of researchers from the University of Massachusetts at Amherst. The physiological signals that can be measured efficiently by the Phyjama include measuring breathing rate, heart rate and in the course of the night the wearer’s sleeping position of wearer as well. The work demonstrated by the researchers gives hope for incorporating such smart advances into regular sleepwear. Various health conditions can be monitored by such new advances that can deliver such biomedical data.
Though, currently there are smartwatches available to measure blood oxygenation and heart rate, they do not sit well with elderly. Moreover, while sleeping such watches are not preferably worn by people due to the inconvenience they happen to pose while sleeping. Given such issues, one cannot deny the natural ease with which a smart pajama can be worn without disrupting the wearer’s sleep and additionally can also be worn otherwise.
As convenient as using them sounds, developing them was a whole different task. To get optimal signal, such monitoring devices need to be as close as possible to the wearer’s skin, while pajamas are typically loose in fit in keeping with their objective of being comfortable while sleeping. To address this issue, the pajamas all around have been integrated with triboelectric sensors so that at least a part of the body is always pressing against these sensors even while the wearer is asleep at night. The minute alterations in pressure are measured by these many sensors which wit physical contact get activated; and further a correlation is set by the body parameters.
Positive outcomes were obtained when the device was tested in natural and controlled environment.
