A remote optical measurement configuration demonstrates the ability to simultaneously monitor multiple vital signs and biomedical indicators, offering a potentially low-cost sensing solution.
An optical approach to the extraction and separation of remote vibration sources has recently been proposed. The technique has previously been applied successfully to biomedical measurements including pulse pressure, heart rate, blood glucose and alcohol concentrations, and intraocular pressure. In this paper, we review this optical sensing technology and demonstrate its ability to monitor three additional biomedical indicators, breathing, blood oximetry, and blood coagulation, as well as its ability to simultaneously monitor indicators that were previously only monitored separately. The proposed compact and potentially low-cost biomedical sensor can be highly beneficial given the global healthcare challenges, especially in the developing countries.
