New Sensors

A dual fiber-optic sensor for the simultaneous determination of bromide and iodide is successfully demonstrated. The device is based upon the dependence of quenching effects on individual fluorophores (quinine and harmane) and quenchers (bromide and iodide). From the point of view of practical application, n unknown analyte species should be able to be determined with a sensor array which contains n sensor elements on which n fluorophores are immobilized. The relative error of the new sensors for the determination of bromide and iodide is less than 5%. The sensor combination is reversible and exhibits an overall response time of 2 minutes. The interference of several ions on the sensors has been studied.

Torsion Deformation

Curvature fiber optic sensors are a kind of novel low cost sensors that can detect curvature directly and distinguish the positive bending and negative bending. This kind of sensor is used to detect torsion deformation of shaft in this paper. The optimal direction of curvature fiber optic sensor was analyzed in osculating plane and rectification plane and maximal sensitivity was gained. The results show that sensor response to the torsion angle is linear approximately. Torsion angle, curvature and bending direction of shaft were measured simultaneously by using curvature fiber optic sensors.
