Prototype and feasibility study of a PVDF infant health monitor
Joe Higgins, E. Carr Everbach · The Journal of the Acoustical Society of America · 1991
Piezoelectric polymer sheets, placed on the floor of a crib, can produce an output voltage that provides information about the heart and breathing rates of an infant in the crib. Such a device could be useful in detecting Sudden Infant Death Syndrome or other infant health problems. A prototype device has been developed with conditioning and detection electronics to isolate the contributions of each signal, and a feasibility study was developed to indicate whether such a device could be made cheaply and reliably enough to be commercially available to a wide population of consumers.
