Resumen
El estudio de fuentes alternativas de energía eléctrica ha experimentado un importante crecimiento en todo el mundo y son una opción energética para los dispositivos electrónicos de baja potencia que requieren baterías para su funcionamiento. Diferentes tipos de energías presentes en el ambiente son consideradas como posibles soluciones energéticas y otras fuentes como las basadas en el cuerpo humano muestran un futuro prometedor. El cuerpo humano es un depósito de energía, cada función vital o actividad que realiza puede ser tomada como posible fuente energética. Caminar o marchar es una actividad física que se puede aprovechar para convertirla en fuente eléctrica útil, mediante el uso de transductores piezoeléctricos, los cuales resultan apropiados para implementarlos en vestuario y calzado. Los materiales piezoeléctricos cuando son sometidos a una deformación mecánica generan un campo eléctrico y viceversa. Cuando una persona camina, al asentar la planta del pie sobre una superficie se hace la presión necesaria para generar una campo eléctrico, si se tiene un material piezoeléctrico como elemento de transducción. En este trabajo se estudia el proceso de captación de energía a partir del ciclo de marcha humana como una fuente alternativa de energía eléctrica mediante la conversión con un dispositivo de transducción eléctrica.
The study of alternative sources of electricity has grown dramatically worldwide and are an energy option for the electronic devices of low-power that require batteries to operate. Different types of energies present in the environment are being considered as energy solutions, and other sources, such as based on the human body show a promising future. Human body is an energy repository, every vital function or activity realized could be considered as a possible energy source. To walk is a physical activity which could be considered as a possible energy source harnessed to turn it into useful electrical power by using piezoelectric transducers as the most appropriate devices to be used on clothes and footwear. Through the mechanical piezoelectric deformation is generated an electric field as well as in the contrary situation. Settling the sole on a surface induces the necessary pressure to generate an electric field by using a piezoelectric as transduction device. This paper presents a compilation about the energy harvesting process from the human displacement from walking movement as an alternative source of electric energy through conversion into electrical power by electrical transduction device.
