Abstract
Tactile sensors are required for the implementation of advanced mechatronic systems, such as in robotics, virtual reality or medical applications, allowing point or distributed measurements by the physical contact between sensor and object. Even thought several technologies have been proposed (based on resistive, capacitive, optical, and magnetic principles), such devices present limitations in terms of performance, cost, and robustness. Alternatively, optical fiber sensors are considered promising technologies, presenting high sensitivity, compact size, and distributed sensing capability. In this context, present Research Project proposes the development of fiber tactile sensors based in 3 measurement principles: intensity, wavelength and specklegram analysis. The transducers will be integrated to optoelectronic signal interrogation systems, and the point or distributed sensors will be characterized according to their static and dynamic responses. After defining the calibration curves, the information acquired by the sensors will be processed by artificial neural networks, and then displayed by a graphical user interface. In addition, the tactile devices will be eventually integrated to glove-based sensors, aiming applications in haptics and rehabilitation systems. The project will provide a high sensitive, robust and low cost sensing solution of relevance for the photonics, robotics and automation industries in Brazil, and also academic results with notability in terms of originality and interdisciplinarity.
