This study investigates the static and dynamic responses of a new sensor prototype, currently under development, for force measurement. Constructed using carbon nanotubes (CNT) dispersed in an optimised elastomeric matrix, these sensors possess material characteristics that make them suitable for footstep detection. The paper presents the characterisation of a sample and offers a comparative analysis with Force Sensitive Resistors (FSRs), which are among the most commonly used solutions for detecting force changes in footstep applications, particularly in exoskeletons. An evaluation of their performance is provided, suggesting their potential application for this purpose.

摘要

This study investigates the static and dynamic responses of a new sensor prototype, currently under development, for force measurement. Constructed using carbon nanotubes (CNT) dispersed in an optimised elastomeric matrix, these sensors possess material characteristics that make them suitable for footstep detection. The paper presents the characterisation of a sample and offers a comparative analysis with Force Sensitive Resistors (FSRs), which are among the most commonly used solutions for detecting force changes in footstep applications, particularly in exoskeletons. An evaluation of their performance is provided, suggesting their potential application for this purpose.
