Abstract
PURPOSE:To quantitatively grasp pressure distribution and to detect information contained in secular variation of the pressure distribution by applying a voltage to a voltage light emitting element made of a phosphor and a rubber material and measuring a light intensity distribution when pressure is varied. CONSTITUTION:An optically transparent conductive substrate 1 is prepared by spraying a tin chloride-ethanol solution to which antimony chloride is added at a specific rate is added on a heated substrate made of hard glass and coating the substrate with a film of the tin oxide doped with the antimony. Further, a film 2 made of silicone rubber to which a phosphor doped with zinc oxide is added at a specific rate is provided on this substrate 1, aluminum is vapor- deposited to provide an electrode 3, and then the surface is coated with an insulating film 4 to form a voltage light emitting element. Then, the voltage light emitting element is applied with a voltage from a power source 5 and pressure is applied by a double cylinder type body 6. The film 2 at the part applied with the pressure shrinks, the distance between electrodes decreases, and the electric resistance of the film 2 varies, so that the light emission intensity of the phosphor increases. The increase in light emission intensity is observed through the substrate 1 to detect the pressure distribution.
