A Sensitivity Analysis of Biophysiological Responses of Stress for Wearable Sensors in Connected Health

IEEE Access, 2021

Stress is known as a silent killer that contributes to several life-threatening health conditions such as high blood pressure, heart disease, and diabetes. The current standard for stress evaluation is based on self-reported questionnaires and standardized stress scores. There is no gold standard to independently evaluate stress levels despite the availability of numerous biophysiological stress indicators. With an increasing interest in wearable health monitoring in recent years, several studies have explored the potential of various biophysiological indicators of stress for this purpose. However, there is no clear understanding of the relative sensitivity and specificity of these stress-related biophysiological indicators of stress in the literature. Hence this study aims to perform statistical analysis and classification modelling of biophysiological data gathered from healthy individuals, undergoing various induced emotional states, and to assess the relative sensitivity and spe...

Multimodal, Idiographic Ambulatory Sensing Will Transform our Understanding of Emotion

Affective Science

Emotions are inherently complex – situated inside the brain while being influenced by conditions inside the body and outside in the world – resulting in substantial variation in experience. Most studies, however, are not designed to sufficiently sample this variation. In this paper, we discuss what could be discovered if emotion were systematically studied within persons ‘in the wild’, using biologically-triggered experience sampling: a multimodal and deeply idiographic approach to ambulatory sensing that links body and mind across contexts and over time. We outline the rationale for this approach, discuss challenges to its implementation and widespread adoption, and set out opportunities for innovation afforded by emerging technologies. Implementing these innovations will enrich method and theory at the frontier of affective science, propelling the contextually situated study of emotion into the future.

Nanobiosensors: towards real-time human monitoring in aerospace medicine and other extreme conditions

MSc Nanomedicine - National and Kapodistrian University of Athens, 2020

Biosensors are promising tools for achieving point-of-care, real-time, human health, and performance monitoring. Nanotechnology can catalyze the process of biosensors miniaturization or can be used for inventing whole-new types of biosensors. The development of nanobiosensors, along with the maturation of artificial intelligence and Internet-of-Things applications, can inaugurate a new era for in-situ predictive diagnostics, telemedical practice, and general scientific understanding. This potential is of particular interest for medical fields responsible to ensure human health, safety, and performance in extreme environments, with utmost example: manned spaceflight and planets habitation. This review focuses on biosensing approaches in space, but extends further to biosensing applications in aviation, military, and sports, as other situations of extreme environmental conditions for the human body. Lastly, some miscellaneous types of nanobiosensors are mentioned, in order to provide an insight of the potential that future biosensing systems hold. Hopefully, this work will encourage nanobiosensor developers to work closely with the end-users, so that quality-by-design can be achieved, and thus the full potential of this next-generation technology can be harvested.

The Current State of Optical Sensors in Medical Wearables

Biosensors

Optical sensors play an increasingly important role in the development of medical diagnostic devices. They can be very widely used to measure the physiology of the human body. Optical methods include PPG, radiation, biochemical, and optical fiber sensors. Optical sensors offer excellent metrological properties, immunity to electromagnetic interference, electrical safety, simple miniaturization, the ability to capture volumes of nanometers, and non-invasive examination. In addition, they are cheap and resistant to water and corrosion. The use of optical sensors can bring better methods of continuous diagnostics in the comfort of the home and the development of telemedicine in the 21st century. This article offers a large overview of optical wearable methods and their modern use with an insight into the future years of technology in this field.
