Existing health monitoring systems detect either acute health issues or long-term deterioration of health. This paper presents a validation concept for sensors and algorithms that detect emergencies and monitor long term health development. The reviewed ambient monitoring system combines a short term rule based and a long term scoring approach that are validated in a study with 100 households. The resulting dataset is complemented by diaries and participation of care givers. Care givers monitor the health state through questionnaires and by rating generated alerts and warnings. The validation benefits from this multilateral approach and points towards a further integration of long and short-term monitoring.
Contactless capacitive ECG measurement is an unobtrusive way of acquiring cardiovascular data. However, movement artifacts present a common problem with this technique. A means of assessing signal quality and confidence is therefore desirable. In this paper we present a capacitive ECG measurement system with an integrated module that constantly monitors the electrode-body-impedance. Moreover, we present a method to derive an artifact level signal from this electrode-body-impedance that can be used to estimate the signal quality of the capacitive ECG measurement. First results of measurements with this system are shown.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
