Respiration during sleep is one of the indicators of an individual’s health. However, many respiratory measurement devices need to be worn by the patient and can affect sleep. We introduce here a novel, easy-to-use, respiratory rate-monitoring sensor made of stretchable piezoelectric material that can be used conveniently at home as well as in a clinical setting.
We enrolled 6 members of a family as volunteers ranging in age from 9 months to 69 years. The sensor was used to continuously record respiratory rate data for all individuals during sleep.
The sensor could detect known breathing patterns such as stable, unstable, or deep breathing as well as apnea during sleep. We observed significant differences in the respiratory rates and respiratory stability between subjects during sleep.
The piezoelectric sensor was effective in people in all age groups, paving a way for future use as a convenient and reliable mode of respiratory assessment for adults as well as neonates at home and in a clinical setting.
