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.
