Abstract

A sensor (1) comprises light emitting means (3) and light receiving means (4) located at opposite ends of a flexible passage (2), filled with a material (6) which may be a solid, liquid, or gas (e.g. air). Bending or deformation of the passage alters the amount of light received by the light receiving means from the light emitting means, thereby providing an indication of the extent of deformation or bending of the passage. A plurality of such sensors may be arranged to define a matrix. Such a sensor or sensor matrix may be incorporated in an item of clothing such as, a shoulder pad, to monitor forces and/or bending stresses on the human body while performing a task. Such a pad could be utilised for enabling the forces exerted on the shoulder of a player during a rugby scrum to be monitored to facilitate correct training of players in scrummaging techniques.
