Tecnologías de captación de energía
Captación de energía tecnologías permitir sistemas autosuficientes convirtiendo la energía ambiental en energía eléctrica para diversas aplicaciones.

Las tecnologías de captación de energía convierten la energía ambiental en energía eléctrica utilizable, lo que permite disponer de sistemas autosuficientes sin fuentes de energía externas. Los nanogeneradores piezoeléctricos y triboeléctricos captan las vibraciones mecánicas y las fuerzas de fricción, mientras que los generadores termoeléctricos aprovechan los gradientes de temperatura para suministrar energía de forma continua. Los métodos fotovoltaico y electromagnético aprovechan la energía solar y de radiofrecuencia, respectivamente, ampliando los ámbitos de aplicación. La integración con redes de sensores inalámbricos y IoT exige circuitos eficientes de gestión de la energía y soluciones de almacenamiento de energía. Los avances en nanomateriales y sistemas microelectromecánicos mejoran la eficiencia de la conversión y la miniaturización. La captación de energía a partir del movimiento humano y de fuentes ambientales favorece wearable y aplicaciones de teledetección.
