Enhancement of the Triboelectrification Using Artificial Surface Charges

Abstract

La triboelectrificación es una tecnología novedosa para cosechar electricidad a partir de energía ambiental sin explotar. Su eficiencia depende del área, la morfología y las cargas en las superficies en contacto. Muchos estudios se llevan a cabo con el fin de aumentar la eficiencia de los generadores triboeléctricos mediante el aumento de la superficie o la variación de la morfología, pero la densidad de carga no está correctamente enfocada hasta la fecha. Aquí, discutiremos el efecto de las cargas artificiales inducidas en la superficie en contacto. Para ese propósito, se utilizó el tratamiento con plasma para aumentar la densidad de carga superficial de la superficie en contacto. El incremento en la densidad de carga en realidad nos ayudó a aumentar la eficiencia del generador triboeléctrico incluso sin cambiar las dimensiones del dispositivo. La potencia de salida se incrementó hasta dos veces en comparación con el dispositivo no tratado. Al final, también cargamos el condensador para comparar las eficiencias de almacenamiento de carga de ambos dispositivos. Encontramos que el dispositivo no tratado y el dispositivo tratado con plasma (15 min y 30 min) almacenaban voltajes de hasta 6 V, 9 V y 12 V respectivamente. Este tipo de estudio seguramente ayudará a los investigadores a mejorar la eficiencia de generación de corriente triboeléctrica incluso sin aumentar el tamaño del dispositivo.

La triboélectrification est une nouvelle technologie pour récupérer l'électricité à partir d'énergie environnementale inexploitée. Son efficacité dépend de la surface, de la morphologie et des charges sur les surfaces en contact. De nombreuses études sont menées afin d'augmenter l'efficacité des générateurs triboélectriques en augmentant la surface ou en faisant varier la morphologie mais la densité de charge n'est pas correctement focalisée jusqu'à ce jour. Ici, nous discuterons de l'effet des charges artificielles induites sur la surface en contact. À cette fin, un traitement au plasma a été utilisé pour augmenter la densité de charge superficielle de la surface en contact. L'augmentation de la densité de charge nous a en fait aidés à augmenter l'efficacité du générateur triboélectrique même sans changer les dimensions de l'appareil. La puissance de sortie a été augmentée jusqu'à deux fois par rapport au dispositif non traité. À la fin, nous avons également chargé le condensateur afin de comparer l'efficacité de stockage de charge des deux appareils. Nous avons constaté que le dispositif non traité et le dispositif traité au plasma (15 min et 30 min) stockaient des tensions allant jusqu'à 6 V, 9 V et 12 V respectivement. Ce type d'étude aidera sûrement les chercheurs à améliorer l'efficacité de la génération de courant triboélectrique même sans augmenter la taille de l'appareil.

Triboelectrification is a novel technology to harvest electricity from unexploited environmental energy. Its efficiency depends on the area, morphology and charges on the in-contact surfaces. Many studies are carried out in order to increase the efficiency of the triboelectric generators by increasing the surface area or varying the morphology but the charge density is not properly focused until date. Herein, we will discuss the effect of the artificial charges induced on the in-contact surface. For that purpose, plasma treatment was used to increase the surface charge density of the in-contact surface. The increment in the charge density actually helped us to increase the efficiency of triboelectric generator even without changing the dimensions of the device. The output power was increased up to two folds as compared to the untreated device. At the end, we also charged the capacitor in order to compare the charge storing efficiencies of both devices. We found that the untreated device and the plasma treated device (15 min and 30 min) stored voltages up to 6 V, 9 V and 12 V respectively. This type of study will surely support the researchers to enhance the triboelectric current generation efficiency even without increasing the size of the device.

كهربة الأطراف هي تقنية جديدة لحصاد الكهرباء من الطاقة البيئية غير المستغلة. تعتمد كفاءته على المنطقة والمورفولوجيا والشحنات على الأسطح الملامسة. يتم إجراء العديد من الدراسات من أجل زيادة كفاءة المولدات الكهربية الثلاثية عن طريق زيادة مساحة السطح أو تغيير الشكل ولكن لا يتم تركيز كثافة الشحنة بشكل صحيح حتى الآن. سنناقش هنا تأثير الشحنات الاصطناعية المستحثة على سطح التلامس. لهذا الغرض، تم استخدام معالجة البلازما لزيادة كثافة الشحنة السطحية للسطح الملامس. ساعدتنا الزيادة في كثافة الشحنة في الواقع على زيادة كفاءة المولد الكهربائي حتى دون تغيير أبعاد الجهاز. تمت زيادة طاقة الخرج إلى طيتين مقارنة بالجهاز غير المعالج. في النهاية، قمنا أيضًا بشحن المكثف لمقارنة كفاءة تخزين الشحنة لكلا الجهازين. وجدنا أن الجهاز غير المعالج والجهاز المعالج بالبلازما (15 دقيقة و 30 دقيقة) يخزنان جهدًا يصل إلى 6 فولت و 9 فولت و 12 فولت على التوالي. من المؤكد أن هذا النوع من الدراسة سيدعم الباحثين لتعزيز كفاءة توليد التيار الكهربائي حتى من دون زيادة حجم الجهاز.
