The growing number of chronic diseases have stretched the healthcare sector. Globally, more than 36 million deaths per year are attributed to chronic disease complications. This has increased the demand for telemedicine in managing chronic patients as they must be on continuous monitoring for a long time. The involvement of wireless sensor networks and cloud computing technology in the health sector is increasing due to the potential it possesses in remote sensing and monitoring applications. This paper presents a developed system prototype for monitoring the heartbeat rate and body temperature of chronic patients using sensors. The monitored data are sent to a cloud database in real-time via an internet connection using the ESP8266 wireless module. The approach involves connecting a heart pulse sensor, an MLX90614 contactless temperature sensor, and the ESP8266 module to the Arduino development board. The goal of this work is to create a system that interfaces chronic patients and medical personnel in an attempt to avert the effects of insufficient health facilities, especially in rural Africa. The patient’s data in the cloud database can also be retrieved by medical personnel anytime in order to track the patient’s conditions and to advise the patient accordingly. The sensed heartbeat and body temperature readings were processed, sent, and recorded in the cloud database effectively.
Mobile phones have become the most popular and the fastest means of communication as a result of the substantial reduction in their prices in recent years. However, these mobile phones use rechargeable battery which requires recharging, this is challenging because of the insufficient electricity supply and alternatives. In Uganda, only 28% of the population is currently having access to electricity and less than 7% of the rural population has electricity service. Telecommunication companies have provided network coverage to almost the entire country with GSM 2G coverage at 93%. The mobile phone users in the rural areas are however few because of inadequate electricity and burden of long distance travelling to town centers in order to charge the phone batteries. This study opts for a power source alternative based on using microwave harvesting. The approach is to convert the microwave signal of 900MHz frequency band from the existing telecommunication downlink frequency into DC voltage. The design is based on the spiral antenna for receiving the 900MHz frequency band. The design is divided into two main parts, namely antenna and charge pump voltage doubler. The spiral antenna is used to harvest and convert the microwave signals into electrical signals; the charge pump helps to convert the low AC to DC voltage capable of charging the battery. The simulation design is tested with Multisim simulation software and the results revealed 5V of DC power generated by means of seven stages voltage doubler. Thus, an alternative source of power for mobile phone battery charging.
