Huang YT, Huang SC, Hsu CC, Chao RM, Vu TK - Sensors (Basel) (2012)

Bottom Line: All of the micro-fabrication was compatible with the standard IC process.Experimental results indicated that the gauge factor of the proposed strain sensor was larger than 4.5, approximately 2.0 times greater than those of commercial gauges.The results also demonstrated that the gauge factor is small when the growth time of SWCNNs is lengthier, and the gauge factor is large when the line width of the serpentine pattern of SWCNNs is small.

ABSTRACT
This study presents a novel flexible strain sensor for real-time strain sensing. The material for strain sensing is single-walled carbon nanonets, grown using the alcohol catalytic chemical vapor deposition method, that were encapsulated between two layers of Parylene-C, with a polyimide layer as the sensing surface. All of the micro-fabrication was compatible with the standard IC process. Experimental results indicated that the gauge factor of the proposed strain sensor was larger than 4.5, approximately 2.0 times greater than those of commercial gauges. The results also demonstrated that the gauge factor is small when the growth time of SWCNNs is lengthier, and the gauge factor is large when the line width of the serpentine pattern of SWCNNs is small.

f8-sensors-12-03269: SWCNNs strain sensors and commercial strain sensors measurement.

Mentions: In tensile testing, a commercial strain sensor was used to measure the strain of the test piece. Figure 8 shows the resistance variation and strain variation of a commercial strain sensor and the SWCNNs strain sensor (with growing time of 20 min, line width of 10 μm). Figure 8 shows that, within 0 to 15 s, no variation of resistance of commercial strain sensor occurred; however, a slight variation resistance of SWCNNs strain sensor was observed.
