San Diego—A proof-of-concept study has shown that mechano- and photoplethysmography (MPG and PPG) can be combined in conventional oximeter sensors. According to the research, the combination could offer a new approach to signal quality assessment and possibly even new physiologic information.
What’s more, said Christian L. Petersen, PhD, piezoelectric elements are inexpensive, making this a viable addition to clinical oximeter sensors.
“Our findings show that a piezoelectric
