Perspective about Cellulose-Based Pressure and Strain Sensors for Human Motion Detection

Abstract

High-performance wearable sensors, especially resistive pressure and strain sensors, have shown to be promising approaches for the next generation of health monitoring. Besides being skin-friendly and biocompatible, the required features for such types of sensors are lightweight, flexible, and stretchable. Cellulose-based materials in their different forms, such as air-porous materials and hydrogels, can have advantageous properties to these sensors. For example, cellulosic sensors can present superior mechanical properties which lead to improved sensor performance. Here, recent advances in cellulose-based pressure and strain sensors for human motion detection are reviewed. The methodologies and materials for obtaining such devices and the highlights of pressure and strain sensor features are also described. Finally, the feasibility and the prospects of the field are discussed.

Advanced Flexible Materials from Nanocellulose

“…Very recently, they summarized the advances in cellulose-based pressure and strain sensors for human motion detection. [31] Ni et al [32] summarized the most recent works on nanocellulose-derived sensors in different forms (1D, 2D, and 3D), highlighting the influence of nanocellulose on the sensing performance. Zhang et al [33] reviewed the recent progress on nanocellulose-based composites and their specific application in energy storage devices.…”
