Investigating the Role of Length in Bio-Polymer-Derived Active Deformation Sensors

In recent years, growing concerns about the environmental footprint of electronic devices, measurement systems, and sensors have driven the search for sustainable technologies. Polymeric composites have emerged as promising materials for the development of advanced sensing systems. However, many of the proposed solutions remain environmentally unfriendly or fail to provide satisfactory transduction performance. There is therefore an urgent need for new materials and technologies that enable the production of greener, high-performance devices that can be easily recycled or safely disposed of. In previous work, the authors extensively investigated Bacterial cellulose-based composites as viable candidates for the fabrication of sustainable active deformation sensors. In this paper, the role of length in the transduction capabilities of such sensors is investigated.
