Point of care diagnostics are medical tools or devices that can diagnose diseases in a community, which is usually in low resource environments. By moving disease diagnosis to the community level, point of care diagnostic devices can save patients money, because they will no longer travel to clinics and capable for earlier diagnosis. Point of care diagnostic systems gives regular standards of producing devices that time, accuracy and cost are reliable. For this purpose it is important that the biosensor be small, rapid and very simple to use. The low cost and ease of use application will increase the market economy. This increase will lead to expanded application in the clinical diagnostic environment. According to the World health organization,

Continuous monitoring is required for critical cardiac patients to ensure superior treatment. With the progress in electronic and adhesive technologies several long term wearable ECG monitors have been developed which requires no wires to operate. This emerging technology ensures incredible mobility and maximizes the comfort level for the patient. These monitors can operate as either recorders or wireless streaming devices. As some cardiac diseases have transient and irregular characteristics in ECG performance, long term wireless devices have empowered the physicians to diagnose the patients more precisely. To improve device performance and increase patient compliance several groups have been working on wearable monitors. In this paper, a

The system presented wireless network for monitor, communication, control and powering of the left ventricular assist device systems which is a novel and significant research for LVADs implantation [1]. However, if there are not internet access and wireless network (via smartphone) at the same time due to malfunction in antenna or network, limitation in range and other issues, the proposed system will fail to monitor and control the LVAD in patients, and therefore it will result in dangerous conditions or death.

There are many improvements that ingestible sensors can address in the health care industry. A patient’s vital signs can be simply listened to through the ingestible sensor in the gastrointestinal tract. The ingestible sensors would be especially useful for patients who it is painful for their skin to be touched as in the case of a burn victim. It also improves the care for patients who have difficulty undergoing different procedures such as a colonoscopy. This could make it easier and more convenient for a person to undergo procedures. The device could have a monumental impact on healthcare providers such as nurses and doctors because the device can continuously monitor vitals. It can be used to treat chronic illnesses, monitor soldiers in

With technology on the rise, an app was chosen as the medium as opposed to the standard technique of feeling a pulse on the neck, wrist, or chest or machine which are commonly used (Ace Fitness, n.d.) However, even with various advancements being made constantly, especially in the technological and medical field, the current products are not without flaws. The requirements of the app were simple, it had to be available on the App Store, display readings that were accurate as possible, easy for one to operate for themself, and be preferably free. Several credible websites happened to have posted lists in which they went through popular apps that monitor heart rate, tried them out, and then used their findings to rate them based off of their efficiency and accuracy. Some common faults shared by apps, for example, small movements and even deep breaths were able to throw off the reading and having to carry out multiple attempts to reach a correct reading (Addictive Tips, December 23, 2014). After searching multiple websites, the best choice ended up being a free app called Heart Rate created by Azumio, as it received top ranking on all the websites it was featured on. After trying the top two top apps mention from reviews, Heart Rate by Azumio and Runtastic, Heart Rate by Azumio was selected as the app that will be used throughout the experiment due to it’s simple and user friendly technique, it’s ability to import personal information, such as birtdate and gender, and as well as the fact that it was raked most accurate and convenient on the review websites ( iMore, April 16, 2015; iTunes,

\textbf{Tier 1}, Intra-BAN, consists of the sensor and actuator node that is placed on the body and implanted. The design of Tier 1 is critical due to it directly interacts with a human body \cite{chen2011body}. The key components of Tier 1 devices are sensor node, actuator node, and \ac{cDAQ}. The sensor node consists of sensors and transmitter. This node digitises the physical information, including user’s vital signs and environmental information, and then transmits to the \ac{cDAQ}. Some sensor nodes use a \ac{MCU} for pre-data processing before sending data to \ac{cDAQ} on the sensor node. Similarly, an actuator node consists of actuators and transmitter. The actuator node changes digitise data into physical action to control the environmental variables. When the \ac{MCU} is used, the actuator nodes can calculate the control signal without communication with a \ac{cDAQ}. The \ac{cDAQ} acts as a hub that collects data from sensor nodes send a control signal to the actuator nodes, processes the data, and transmits to the base

Biopotential signals are electrical activities of the human body systems which are measured by potential fluctuations between points in living cells, tissues and organisms .In medicine field, certain biopotential signals are important as they are considering diagnosis and patient monitoring. These signals represent the activity of particular organs such as the heart, brain, muscles and many more. With the help of specialised electrodes, biopotential signals transduce low-noise and artefact-free signals to the organ or the body. A basic biopotential amplifier consists of an instrumentation amplifier. The amplifier should have several characteristics such as high amplification, input impedance and the ability to reject any electrical interference. These characteristics are needed to measure biopotentials signals. Other component can be added to the circuit in order to improve the signals; filter can be added to reduce electric interference, electric isolation and defibrillation shock protection. The electrical activity can originate from different tissues and organs sources. There are different sources of biopotential signals such as EEG, ECG, EMG; they are all based on the same principles however the signals will have smaller amplitudes. Electroencephalogram (EEG) records the electric activity of the

This project will make a significant contribution to knowledge in the modelling and design of a non-invasive medical condition monitor using physiological responses. In particular, the project aims to:

The Heartbeat sensor works on the principle of photoplethysmography which is a method of not invading the body for measuring heartbeat. It provides a simple way to obtain the function of the heart. The heartbeats can be measured based on the principle of psycho-physiological signal which is used as a stimulus for the virtual- reality system. The blood flow in the finger changes every instant. The sensor shines a small very bright LED through the clip and measures the light that gets transmitted to the Light Dependent Resistor. The signal firstly gets amplified after which it is inverted and filtered. In order to calculate the heart rate based on the blood that flows to the fingertip, the sensor is connected to a LM358 OP-AMP for observing the heartbeat pulses. The module gives a direct output digital signal when connected to a microcontroller. It is compact in size and works at a

Applications of low power integrated intelligent sensors [1–5] has been prolific in recent years, for instance in environmental observation [8–10], security surveillance [11] and infrastructure communication [12], and biomedical and healthcare monitoring [6, 7]. In particular, as the baby boomers enter retirement, medical cost becomes significant. For example, in 2014, health care accounted for 20% of federal spending in the U.S. []. A major problem in current healthcare systems is that sensing and processing medical data require significant resources. In order to alleviate this problem, wearable medical devices are expected to provide automatic monitoring and processing of physiology signals, and more importantly, identifying abnormal signals and contact medical systems for help if necessary, as shown in Fig. 1. Although such sensors usually have wireless data communication capability through body area network, due to limited battery power supply, sending raw sensed data is usually not an option. This is because that in a wireless sensor, usually radio communication power is much higher than signal processing power []. Thus, it is expected that the sensors are capable of providing preprocessing of raw data based on DSP algorithms and just sending the processed results. Such sensors are called ”intelligent sensors” []. Besides the capability of signal processing and wireless communication, low power, high accuracy, high reliability, and small footprint are also listed as
