PSI has developed a Smart Medical Sensor System (SMSS) that has several advantages over current medical diagnostic equipment. With its high resolution, sensitivity, SNR and wide bandwidth capability, it can be utilized in non-invasive medical diagnostic equipment to detect abnormalities at frequencies never before utilized – 0.001 to 5 Hertz. The high SNR capability provides strong, uncluttered human vital sign signals for extraction of useful information without the need for complex software algorithms and the associated costly electronics.
