Revisión sistemática de literatura sobre mecanismos de recolección de energía utilizados en dispositivos de monitorización de signos vitales

Vital signs monitoring devices play a crucial role in the medical field by enabling continuous patient tracking. However, these devices rely on batteries or an electrical power supply, which can present limitations and inconveniences such as data loss and interruptions in continuous monitoring. Nevertheless, the increasing implementation of autonomous energy harvesting mechanisms may replace conventional power sources. This systematic literature review was conducted to identify the most appropriate energy harvesting mechanisms for vital signs monitoring devices in living organisms. The analysis included both environmental sources and those generated by the human body. Information was also provided on the most commonly monitored vital signs and the device's location on the body. Additionally, the energy output generated by the technologies considered in the analyzed publications was specified. The most used mechanisms were triboelectric and piezoelectric, while radiofrequency and triboelectric methods achieved higher energy production. It is worth noting that the evaluated mechanisms apply to both humans and other living beings, as they share certain similarities with domestic animals.
