On the Report of Performance Analysis of Electrospun Carbon Nanofibers based Strain Sensor for Applications in Human Motion Monitoring

摘要

Flexible and wearable sensors are currently beingextensively used in versatile applications including wireless bodyarea network. Specifically, such sensors are mostly incorporated toyield a linear response within their range of operations. A recentlydeveloped flexible and wearable resistive strain sensor made ofelectrospun carbon nanofibers has been reported with a gaugefactor up to 72. In this paper, the performance of the strain sensorembedded in a polyurethane matrix was studied at first. A linearregion of operation of such sensor was defined from directmeasurements for wireless body area network applications. Theequivalent analytical expressions were established and reported.
