Development of a Portable GSM SMS-Based Patient Monitoring System for Healthcare Applications

Although health care is a vital problem in recent years mobile communication has become a widespread part and parcel of everyday life even in the rural areas of developing countries This paper proposed a model to include the mobile communication for monitoring vital signs of health such as blood pressure heart rate body temperature blood glucose level and sends result as Short Message Service SMS for the physician so as to monitor their patients continuously Cuffless pressure sensing transducer is taken into consideration to measure pressure pulse and then combined with oscillometric method to measure Blood Pressure BP Availability of different sensors and measurement techniques to determine heart rate is presented Conventional glucometry in low cost electronics and body temperature measurement using electronic thermistor is also described here Sensed parameters are processed and stored into an array in ARM7 processor and sent via GSM SIM300 Modem This portable vital sensing system is useful to analyze daily health condition can be used both in home and hospital to prevent Hypertension Heart Attack and to control Diabete

Energy Harvesting in Implantable and Wearable Medical Devices for Enduring Precision Healthcare

Modern healthcare is transforming from hospital-centric to individual-centric systems. Emerging implantable and wearable medical (IWM) devices are integral parts of enabling affordable and accessible healthcare. Early disease diagnosis and preventive measures are possible by continuously monitoring clinically significant physiological parameters. However, most IWM devices are battery-operated, requiring replacement, which interrupts the proper functioning of these devices. For the continuous operation of medical devices for an extended period of time, supplying uninterrupted energy is crucial. A sustainable and health-compatible energy supply will ensure the high-performance real-time functioning of IWM devices and prolong their lifetime. Therefore, harvesting energy from the human body and ambient environment is necessary for enduring precision healthcare and maximizing user comfort. Energy harvesters convert energy from various sources into an equivalent electrical form. This paper presents a state-of-the-art comprehensive review of energy harvesting techniques focusing on medical applications. Various energy harvesting approaches, working principles, and the current state are discussed. In addition, the advantages and limitations of different methods are analyzed and existing challenges and prospects for improvement are outlined. This paper will help with understanding the energy harvesting technologies for the development of high-efficiency, reliable, robust, and battery-free portable medical devices
