Wearable Master Device Using Optical Fiber Curvature Sensors for the Disabled
نویسندگان
چکیده
This paper addresses a wearable master device for physically handicapped persons whose arms are disabled. Optical fiber curvature sensors are used to measure the human body motion. For the developed wearable master device, a calibration and mapping method of the sensors is proposed to extract 2-DOF human shoulder motions. An experiment shows that the wearable master device can be used for a 2-DOF input device effectively for handicapped persons. It has also shown that a subject can control a mobile robot with the wearable master device.

متن کاملA Novel Low-Cost, Large Curvature Bend Sensor Based on a Bowden-Cable
Bend sensors have been developed based on conductive ink, optical fiber, and electronic textiles. Each type has advantages and disadvantages in terms of performance, ease of use, and cost. This study proposes a new and low-cost bend sensor that can measure a wide range of accumulated bend angles with large curvatures. This bend sensor utilizes a Bowden-cable, which consists of a coil sheath and...

متن کاملAn Optical-Fiber-Based Airborne Particle Sensor
A new optical-fiber-based airborne particle counter is reported. Unlike traditional light-scatter-based techniques, the particle is detected through the drop in optical fiber coupling efficiency as the particle disrupts the electromagnetic mode of the optical beam. The system is simple, substantially smaller than traditional systems, and does not require high power laser input. This makes it at...
