Part of the NIH-IEEE POCT 2017 Special Issue We propose a flexible, dry and antibacterial electrode with low and stable skin electrode contact impedance for bio-potential signal monitoring. We fabricated bacterial cellulose/polyaniline/AgNO3 nanocomposite membrane (BC/PANI/AgNO3) and used it for bio-potential signal monitoring.
Precise dispensing of droplets is a crucial step for acquiring reliable blood diagnostic results. When the source sample volume is limited, the need for precise dispensing of submicroliter and nanoliter quantities is especially important. In this work, we developed a positive-displacement high-precision dispensing technique using a nickel electroformed tube with an inner diameter accuracy of 5 μm or less.
This work introduces a wireless, solid-state, portable, and automated device capable of semi-continuously measuring the total ammonia (ammonia (NH3) and ammonium (NH4 + )) levels of fluids, including biological samples. This device reliably measures the total ammonia of biological samples (e.g., urine) faster than current ammonia quantification techniques.
Accurate segmentation of right ventricle (RV) from cardiac magnetic resonance (MR) images can help doctor to robustly quantify the clinical indices including ejection fraction. In this paper, we develop one regression convolutional neural network (RegressionCNN) that a holistic regression model is incorporated with convolutional neural network (CNN) to determine boundary points’ coordinates of RV directly and simultaneously.
Liquid medication overdose in pediatric patients results in over 70000 visits to the emergency room yearly in the USA. Various studies have demonstrated that the root cause of this high incidence is due to user and device error in dose measurement. The standard measuring cup and syringe suffer from the challenge of accurately measuring and dispensing viscous liquids, which comprise the majority of children’s medication formulations.
Pressure ulcers (PU) are known to be a high-cost disease with a risk of severe morbidity. This paper evaluates a new clinical strategy based on an innovative medical device [Tongue Display Unit (TDU)] that implements perceptive supplementation in order to reduce prolonged excessive pressure, recognized as one of the main causes of PU. A randomized, controlled, and parallel-group trial was carried out with 12 subjects with spinal cord injuries (SCI).
Part of the Special Issue Advanced Internet of Things in a Personalized Healthcare System: Validation, Analysis and Utilization Heart sounds deliver vital physiological and pathological evidence about health. Wireless cardiac auscultation offers continuous cardiac monitoring of an individual without 24*7 manual healthcare care services.
We developed an automated approach for QRS complex detection and QRS duration (QRSd) measurement that can effectively analyze multichannel electrocardiograms (MECGs) acquired during abnormal conduction and pacing in heart failure (HF) and cardiac resynchronization therapy (CRT) patients to enable the use of MECGs to characterize cardiac activation in such patients.
