Herein, we propose a simple fabrication method for MXene-coated V-groove sensors for applications. To enhance the sensitivity ofthis sensor, we applied MXene particles, instead of conventional metal layers, as a sensing material on the sensor's surface. This allowsfor an easier fabrication, as well as higher sensitivity of the sensor compared to those of our previously demonstrated metal-based Vgroovesensor. Additionally, polyurethane-acrylate, a UV-curable liquid polymer, can be easily applied using micro-electromechanicalsystems-based surface-texture micromachining. The sensor sensitivity is approximately 0.08 /mm, and it can be improved by increasingthe number of V-grooves. We believe that the proposed MXene-based wearable sensor offers a great potential in detecting various typesof motions characteristic of human activities.
