Novel design for a wearable, rapidly deployable, wireless noninvasive triage sensor.
This paper presents a unique design for a low-power, continuous non-invasive sensor capable of remotely monitoring the five major vital signs of a patient. In particular, the sensor is designed for rapid attachment to the fingerbase of a patient by utilizing a clip-type mechanism and is comprised of a photoplethysmograph (PPG), a MEMS accelerometer, a temperature sensor, and a wireless node. Although hastily placed by a medic, the finger sensor will automatically find the location of a digital artery and acquire a clear, pulse signal: a micro-sensor array accommodates the location of the sensor attachment. Additionally, the PPG signal, although corrupted with the patient's motion in chaotic environment, will be recovered by using the MEMS accelerometer and an Active Noise Cancellation algorithm.
