Analysis Of Power Supply Methods For Wireless Biomedical Sensors And Future Development Prospects

Implantable biomedical devices have been designed to provide monitoring and diagnosis of the physical information in human bodies. The population is ageing and there are many increasing chronic diseases at all ages all around the world, that’s why modern methods of diagnosis and monitoring chronic diseases play a vital role in medicine and human health. Biomedical wearable devices and implantable devices are in high demand due to their wider applications. Wireless powering methods can improve the way a patient’s health can be monitored and also help patients who are living far from the hospitals. The current thesis has been focused on the analysis of wireless powering methods for implantable biomedical sensors, their advantages and drawbacks, requirements of different approaches as well as current and future challenges. In order to implement a wireless powering method, developers have to establish quality management systems in the designing phase, to implement safe and effective devices, and meet the requirements of regulatory authorities. These wireless powering methods and devices can improve quality of life to the patients and extend their lives. However, one of the significant challenges is the power supply, because it is vital to provide sufficient power and to maintain it on the same level along the whole time when the system is operational. Modern wireless IMDs require a stable and continuous power consumption; that’s why this problem becomes significant
