Abstract
Optical fi ber sensors have been developed since 1970’s, and several systems have already been used in practical applications. History of this technological fi eld is reviewed, at fi rst, through looking at the activities shown in the International Conference on Optical Fiber Sensors (OFS). The latest OFS, which was held last year in Beijing, is also reviewed briefly for checking the recent tendency in this field. Then, fi ber optic nerve systems are discussed, as a recent topic among the various types of optical fi ber sensors.
