In a significant advancement for eco-friendly technology, researchers have developed a novel strain gauge that combines the innovative properties of Ti3C2TX MXene with gelatin hydrogel. This breakthrough, reported by Hyun-Gu Han from the School of Electrical and Electronics Engineering at Chung-Ang University in Seoul, presents a biodegradable and healable strain gauge composite that holds promise for various applications, particularly in the construction sector.
The strain gauge, known as MGHC, showcases impressive performance metrics, including a gauge factor close to unity, which indicates a reliable linear relationship between strain and resistance change. This is crucial for accurate measurements in structural health monitoring, where understanding material strain is vital for ensuring safety and longevity. “Our strain gauge not only performs well under different strain levels but also demonstrates remarkable cyclic endurance,” Han noted, emphasizing the device’s potential for long-term use in challenging environments.
With the construction industry increasingly focused on sustainability, the MGHC strain gauge could revolutionize how structures are monitored and maintained. Its ability to endure over 300 cycles with minimal resistance change positions it as a viable alternative to traditional sensors, which often rely on less environmentally friendly materials. The gauge’s sensitivity to stretching speeds further enhances its application potential, allowing for real-time monitoring of structural integrity during various construction processes.
Moreover, the healable property of the MGHC strain gauge opens new avenues for self-repairing technologies in construction. Under optimal temperature conditions, the gauge can restore its functionality after damage, reducing the need for replacements and minimizing waste. This could lead to significant cost savings in maintenance and repair, making it an attractive option for construction firms eager to adopt greener practices.
The biodegradability of the sensor also addresses growing concerns about waste and environmental impact in construction. As the gauge completely degrades in phosphate-buffered saline and diluted hydrogen peroxide solutions, it ensures that any by-products are eco-friendly. This characteristic aligns with the industry’s shift toward sustainable materials and practices, making the MGHC strain gauge not just a technological innovation but a step forward in environmental responsibility.
As the construction sector grapples with the dual challenges of safety and sustainability, the MGHC strain gauge represents a promising solution. Its development marks a pivotal moment in the integration of advanced materials into practical applications, paving the way for a future where construction is not only efficient but also environmentally conscious. This research, published in ‘Materials Research Express’, underscores the potential of combining cutting-edge materials with sustainable practices, setting a precedent for future innovations in the field.
