In this paper, we design a novel two-channel sphygmus monitoring system, which can synchronously measure the pulse signals and their difference one from radial artery and ulnar artery. This system uses the CM-01B vibration sensor as a sphygmus sensor, utilizes the WiFi module to transmit data, makes use of the PC software to process and display real-time data of sphygmus. The pint-sized and portable...
Internet of Things is the new revolution that is going to impact every facet of our lives. Internet of Things (IoT) is the new technology which includes the collection of Sensors, Actuators, processors and other development boards (eg. Raspberry pi, Arduino etc) to collect the data from different sources depending upon domain of application, process the acquired data before sending to distant cloud...
This paper presents a novel approach based on pulse transit time (PTT) for the estimation of blood pressure (BP). In order to achieve this goal, a data acquisition hardware is designed for high-resolution sampling of phonocardiogram (PCG) and photoplethysmogram (PPG). These two signals can derive PTT values. Meanwhile, a force-sensing resistor (FSR) is placed under the cuff of the BP reference device...

A healthcare monitoring system is designed which can be used in the hospitals to monitor people who need to an intensive care. This system can be implemented on many biological signals. ECG signal is selected for put in practice in this work. Since ECG signal is measured in mille volt, it needs to be amplified. Also it is a noisy signal, so it needs to be filtered. ECG acquisition part contains AD620...
We present the architectural design space exploration of a compressed sampling engine for use in a wireless heart-rate monitoring system.

Visual stress which can induce headache, migraines and eyestrain affects our body often detrimentally. Heart rate variability (HRV) analysis is commonly used as a quantitative marker depicting the activity of autonomic nervous system (ANS) that may be related to visual stress. In this paper, we proposed an improved HRV methodology for HRV features extraction and analysis. Firstly, a multi-channel...
