A truly wearable non-invasive blood pressure (NIBP) sensor- light-weight, compact, unobstrusive, and essentially unnoticeable to the patient-could revolutionize healthcare delivered beyond the traditional walls of medical facilities, offering new ways to care for patients in their everyday surroundings. This paper presents results from our work towards the development of a self-contained, wearable...
It is well known that the photoplethysniogram (PPG) is related to the underlying arterial blood pressure (ABP). However, there is ambiguity regarding the precise relationship of these two circulatory signals: some investigators have described a static relationship, while others have used more complex dynamic characterizations. This paper attempts to reconcile these models, employing results obtained...
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...
Wearable sensing networks offer a multitude of benefits for the user. One field that can benefit from such technologies is in-home robotics. Much work has been dedicated to the general area of interaction between robots and humans, and more specifically to gesture recognition. We propose a wearable monitoring network composed of conductive fabrics that can more easily facilitate robot interaction...
This paper presents the underlying principle and accompanying initial validation results towards the development of an optically-based, cuffless blood pressure monitoring method. As opposed to traditional oscillometric techniques, the optical sensor is calibrated with a known patient-controlled hydrostatic perturbation. In particular, the hydrostatic pressure challenge is utilized to parameterize...
This paper provides an appraisal of the sensor requirements and prospects available for the growing field of wearable medical sensors. The results of a literature survey for various sensor use-models indicate that the design goals for each intended sensor application must focus on task specific criteria for ultimate sensor acceptance. Provided use-models include the examination of the relevant medical...
