The use of Force Sensing Resistors for muscle force measurements

Force Sensing Resistors (FSR s) provide a method of quantitatively measuring force. These devices have been characterized, evaluating such factors as reproducibility, linearity, stability, and memory effects to determine their appropriateness for use in clinical and rehabilitative settings. It has been found that these devices work well in measuring forces in isometric systems, but are not well suited for measurement of rapidly changing forces such as finger impact. Characteristics of the FSR s and measurement techniques using these devices will be provided in this paper. Equipment designed using these sensors to determine handgrip force, heel-toe force, and foot drag tendency will be described.
