In recent years, printing technologies have emerged as a game-changer in the field of electronics, offering a shift from conventional fabrication methods. These technologies, collectively known as printed electronics, enable cost-effective and scalable production of electronic components by depositing functional materials onto flexible substrates using additive manufacturing techniques.
Unlike traditional approaches such as photolithography, which involve complex and costly processes, printed electronics offer a simpler, more environmentally friendly alternative. Moreover, the flexibility of printing technologies allows for the integration of electronics into various form factors, enabling the development of lightweight, conformable, and wearable electronic devices.
“This convergence of electronics and printing presents significant potential for revolutionizing industries ranging from healthcare and consumer electronics to automotive and aerospace, paving the way for a future where electronics are seamlessly integrated into everyday objects and environments,” says Karem Lozano Montero.
Self-powered wearable applications
Her doctoral dissertation focuses on the development of electronic devices for self-powered wearable applications, utilizing printed electronics technologies. Her research represents a significant advancement in the field of wearable electronics by addressing key challenges such as power supply constraints, flexibility, and comfort. By fabricating ultra-thin piezoelectric sensors and nanogenerators, the study demonstrates the potential for integrating electronics seamlessly into wearable devices, thereby enhancing user comfort.
“The findings underscore the importance of engineering materials to enhance device functionalities, such as flexibility and stretchability, while also optimizing energy harvesting capabilities,” Karem Lozano Montero summarizes.
In a society increasingly reliant on wearable technology for healthcare monitoring and fitness tracking, the research outcomes hold substantial social relevance as they provide insights into the development of conformable and flexible electronic devices using printed technologies. Consequently, the study contributes to the adoption of printed devices in healthcare applications for continuous monitoring of vital signs or in fitness applications for accurate tracking of physical activity, ultimately improving people's health, well-being, and overall quality of life through the practical application of wearable technology across different aspects of daily living.
