Накратко на български

3D-принтирани устройства от пластмасови отпадъци превръщат движението на тялото и слънчевата светлина в електричество и зелен водород. Това помага за намаляване на въглеродните емисии чрез използване на отпадъци за производство на чиста енергия.

Motion Powered 3D Printed Self-Healable Energy Storage for Wearable Electronics utilizing Plastic Waste

Countries around the globe collectively target ‘net zero-carbon emissions by 2050’. The production of green hydrogen has been considered a pure source of energy without greenhouse gas emissions. So far, the production of green hydrogen is limited to on-shore and off-shore wind turbines and solar panels which are mostly location-specific, and hours of daylight and weather dependent. In this project, we have addressed the generation of green hydrogen from small-scale kinetic energy such as biomechanical actions. Besides, the researcher has demonstrated the fabrication of electro(photo)catalytically active filament using 2D nanomaterials, conductive carbons, and thermoplastic polymer polylactic acid. The 3D printed electro(photo) catalytically active electrodes were used for supercapacitor and water splitting to produce hydrogen using the wide wavelength of the solar spectrum. In brief, the overall objectives of the project were to develop 3D-printed energy storage devices and conversion of low-scale kinetic energy around us to electrical energy followed by green hydrogen production. This whole project brings a novel direction toward the target of the ‘net zero carbon emission’ policy by the EU government through the conversion of waste to wealth.

Цел на проекта

Portable and wearable devices including smartwatches, health monitoring, and multimedia devices are becoming increasingly popular in our daily lives. These devices are generally powered by batteries that have a limited lifetime. Recently, the development of triboelectric nanogenerators (TENGs) has shown to be an effective approach to transforming biomechanical energy to power up these devices. However, TENGs generate low energy and AC signals which limit their use in continuously powering up electronics. The AC signals of TENGs must be converted and stored in energy storage. Among energy storage devices, supercapacitors (SCs) are found to be a promising device due to their high power density, moderate energy density, long cycle life, and safe use. Hence, this project aims to develop an integrated device (TENGSC), connecting a high-performance TENG with an SC, which can store the transformed biomechanical energy. However, the TENG and SC are susceptible to undergoing damage during biomechanical actions. This mechanical damage can be overcome by developing self-healable TENG and SC. The self-healing nature will help to restore their properties if any damage happens during the cyclic movements. Moreover, to harvest high power from the TENG, a 3D printing technique will be followed, which can easily introduce micropatterns on the film surface. The micro-patterns provide higher frictional effect which is the key factor in increasing the conversion efficiency of TENG. Besides, the energy density of the SC can be increased through using porous MXenes –Ti3C2 as electrode materials. This can be developed through the 3D printing of a Ti3C2/graphite–based polyethylene terephthalate (PET) filament followed by pyrolysis. The waste drinking water bottles can be used as PET source. Thus, through this work, biomechanically driven smart power source will be developed along with concept of waste to wealth transformation, which can be used in portable and wearable electronics.
