The Effect of Miss and Tuck Stitches on a Weft Knit Strain Sensor.

Weft knitted conductive fabrics can act as excellent textile strain sensors for human motion capture. The loop architecture dictates the overall electrical properties of weft knit strain sensors. Therefore, research into loop architecture is relevant for comprehensively investigating the design space of e-textile sensors.

A spectrum matching method for accurate frequency estimation of real sinusoids.

It is well-known that incoherent sampling is detrimental for frequency estimation of a real sinusoid, and the estimation errors get worse when the signal lengths are very short. In this paper, a spectrum matching based frequency estimator is proposed as well as evaluated against other four two-step methods developed to suppress the effect of incoherent sampling. The spectral interference introduced by incoherent sampling is eliminated via a spectrum matching process including modulation and spectral analysis.

A modulation based phase difference estimator for real sinusoids to compensate for incoherent sampling.

Phase difference estimation is a fundamental problem in numerous applications. However, incoherent sampling (IS) is an inevitable factor which degrades the precision of many correlations or Fourier transform-based approaches. In this paper, IS and the spectral superposition of real signals are both considered.
