摘要:
A method of using a paint sensor to observe stress distributions of a stressed substrate includes the steps of applying a composition including a paintable medium and a mechanoluminescence material to a substrate, allowing the composition to form a solid film on the substrate, allowing the substrate to be stressed following the formation of the solid film, and measuring the stress the substrate has undergone by determining the mechanoluminescence of the solid film. A composition for visualizing stress or crack distributions includes a paintable medium and a mechanoluminescence material dispersed therein.

A complex material, which emits light with a light hand or finger touch of a person and only when subjected to a stress, comprises stress emission particles and an elastic material. The stress emission particles such as SrAl2O4:Eu particles emit light when subjected to a stress. The elastic material is a soft material having a Young's modulus smaller than 10 MPa, such as silicone rubber, synthetic rubber, natural rubber, or the like. Weight percent of the particles in the complex material is from equal to or more than 10% to less than 100%, ore preferably from equal to or less more than 10% to equal to or less than 90%. The particles are preferably surface-treated by a silane coupling agent. The complex material is used as an artificial light-emitting skin or an artificial light-emitting body.

摘要:
An optically emissive material and, in particular, materials for use in single photon generation technologies, have multiple excited energy states that have different decay rates and can emit photons with different properties. A primary excitation radiation source is configured to apply primary radiation to an optically emissive material to excite the optically emissive material into a primary excited state. A secondary excitation radiation source is configured to apply secondary radiation to a thermal contribution material to generate thermal energy in the thermal contribution material. The thermal contribution material is physically configured to transfer thermal energy to the optically emissive material and excite the optically emissive material from the primary excited state to a secondary excited state for dynamic control of the emission rate, or emitted photon properties, of the optically emissive material.

An inflatable sports ball is provided. The sports ball includes an interior bladder and a cover disposed about the interior bladder. The cover may include an outer substrate and an intermediate structure. The cover may further include an outer substrate surface, defined by the outer substrate, and a feature surface radially spaced apart from the outer substrate surface. Together the outer substrate surface and the feature surface cooperate to define an exterior surface of the cover. A mechanoluminescent material may be embedded in a portion of the cover. The mechanoluminescent material may be disposed at only one of the outer substrate surface and the feature surface, such that it is positioned to form a predetermined design on the cover. The mechanoluminescent material emits visible light in response to an externally-applied stress, such that the predetermined design illuminates when an external stress or mechanical stimulus is exerted upon the cover.

Provided is a display device in a mechanical method using wind, vibration. The mechanoluminescent display device includes a substrate having a predetermined shape, and projections formed with a predetermined pattern on the substrate. The projections are formed of a mixture of a stress luminescent material emitting light by mechanical energy which is applied and a stress transmission material transmitting the mechanical energy applied from the outside to the stress luminescent material.
