Ultra-high-sensitivity two-dimensional bend sensor [PDF]
, 2006 A multicore fibre Fabry-Perot-based strain sensor interrogated with tandem interferometry for bend measurement is described. Curvature in two dimensions is obtained by measuring the difference in strain between three co-located low finesse Fabry-Perot ...

Polarization properties of interferometrically interrogated fiber Bragg grating and tandem-interferometer strain sensors [PDF]
, 2006 Lead sensitivity in low-coherence interferometric fiber-optic sensors is a well-known problem. It can lead to a severe degradation in the sensor resolution and accuracy through its effect on the fringe visibility and interferometric phase.

Flexible Piezotronic Strain Sensor [PDF]
Nano Letters, 2008 Strain sensors based on individual ZnO piezoelectric fine-wires (PFWs; nanowires, microwires) have been fabricated by a simple, reliable, and cost-effective technique. The electromechanical sensor device consists of a single electrically connected PFW that is placed on the outer surface of a flexible polystyrene (PS) substrate and bonded at its two ...
