Chronic diseases quickly become broader public health issues because of the difficulty in obtaining appropriate, often long-term health care. So that, it requires the extension of health care for patients with chronic diseases beyond the clinic to include patient’s home and work environment. To reduce costs and provide more appropriate healthcare, we need telehealth care where internet of things (IoT) technology plays an important role. The integration of the IoT and medical science offers opportunities to improve healthcare quality, and efficiency and to better coordinate healthcare delivery at home and in the workplace. In this paper, we present the realization of a remote healthcare system based on the IoT technology. The function of this system is the transmission via a gateway of internet collected data using biomedical sensors node based Arduino board (e.g., temperature, electrical activity of the heart, heart rate monitor). These data will be stored automatically in a cloud. The health can then be monitored by the doctor or patient using a web page in real-time from anywhere at any time in the world using laptops or smart phones, etc. This method also reduces the need for direct interaction between doctor and patient.

“…SaO2 is defined as the percentage of hemoglobin with bound oxygen and is termed as SpO2 when measured by a pulse oximeter. The average level is 95-100 percent [22]. An oxygen level below 90 percent is considered to below, resulting in hypoxemia [25].…”

“…Optical sensors can detect a limited range of substance concentrations; for example, when detecting pH, they require the addition of absorbable phenol red for colour development and, only in the pH range of 6.5–8.0, linearity reflects well and data are accurate [ 95 , 96 ]. However, optical sensors are advantageous in low-oxygen environments because their measurement data are independent of redox reactions [ 97 , 98 ].…”

Drugs may undergo costly preclinical studies but still fail to demonstrate their efficacy in clinical trials, which makes it challenging to discover new drugs. Both in vitro and in vivo models are essential for disease research and therapeutic development. However, these models cannot simulate the physiological and pathological environment in the human body, resulting in limited drug detection and inaccurate disease modelling, failing to provide valid guidance for clinical application. Organs-on-chips (OCs) are devices that serve as a micro-physiological system or a tissue-on-a-chip; they provide accurate insights into certain functions and the pathophysiology of organs to precisely predict the safety and efficiency of drugs in the body. OCs are faster, more economical, and more precise. Thus, they are projected to become a crucial addition to, and a long-term replacement for, traditional preclinical cell cultures, animal studies, and even human clinical trials. This paper first outlines the nature of OCs and their significance, and then details their manufacturing-related materials and methodology. It also discusses applications of OCs in drug screening and disease modelling and treatment, and presents the future perspective of OCs.

“…Because of the advancement of technology and research, such as spectrophotometry, opt acoustic and transmission spectroscopy, many low-cost and simple non-invasive technologies have emerged. Several researchers had discussed the uses of multi-wavelength pulse oximeters to detect hemoglobin levels, and SpO 2 (29)(30)(31)(32) . Macknet et al evaluated Hb measurement with hemodilution and compared it with pulse CO-Oximeters and invasive laboratory CO-Oximeter Hb measurements which were carried out in both healthy and surgical subjects (33) .…”

Objectives: To develop a non-invasive measurement of continuous monitoring of hemoglobin using IoT-enabled pulse oximetry. Currently in India, most women, senior citizens, and rural area people are suffering from anemia. In many cases, people unable to visit hospitals and laboratories for hemoglobin testing. To help the above people our proposed system will measure hemoglobin concentration without visiting the hospital at an affordable price. Methods: We developed real-time continuous monitoring of Hb concentration and oxygen saturation (SpO 2) using pulse oximetry. In this study, 47 healthy volunteers were participated and measure the above-mentioned parameters under resting conditions. Findings: The obtained results were in unison with laboratory measurements with the variation of 0.12g/dL to 1.0g/dL. Novelty/Applications: Experimental results showed the approach of continuous monitoring of hemoglobin and SpO 2 using an IoT-enabled noninvasive method can be useful in healthcare management.
