Possible to measure 9 independent elastic modulus in a single vibration experiment and analysis without sample machining or surface treatment
The measurement of elastic modulus, which is a fundamental parameter, is essential to characterize the material property. As an example of object with a simple linear shape, such as a stick, the elastic modulus can be obtained experimentally by tensile testing. Today, a wide variety of object with complex shape can be formed due to the recent development of 3D printer technology. On the other hand, the elastic modulus of such object with complex shape having mechanical anisotropy, was difficult to simply measure by the conventional method. This invention is about a simple method for measuring elastic modulus of object with complex shape having mechanical anisotropy. This invention compares at first the vibration mode obtained experimentally by the object resonance frequency using ultrasonic resonance method, with the estimated vibration mode. Then, the elastic modulus is determined after the inverse analysis so that the estimated vibration mode matches the experimental value. The elastic modulus is determined with high precision by applying an algorithmic tip to this comparison. The most significant feature of this measurement method is its simplicity since it requires only one vibration experiment and analysis to measure the 9 independent elastic modulus.
Equipped with bio-battery, electroosmotic flow provides moisturizing effect
With the spread of contact lenses (CLs), the number of patients suffering from dry eye is increasing. In addition, the spread of smart CLs with biomonitoring, communication and display functions is expected in the future, and effective measures against dry eye are required. The present inventors have developed a CL-type device capable of preventing dry eye based on their long accumulated "hydrogel synthesis and molding technology" and "biocompatible battery power generation technology". Specifically, they developed a hydrogel material with high electroosmotic flow generation efficiency and excellent moldability. They found that when applied to CLs, water flow is generated in the lens by energization, which can maintain the wet state of the CL and stabilize the tear film on the cornea. Furthermore, they have succeeded in mounting a bio-battery on a contact lens to drive it as a self-standing device that does not require external power supply (right figure). The present invention is important not only for the prevention of dry eye, but also for the controlled release of eyedrops and the control of intraocular pressure by inducing aqueous humor drainage. It is expected to develop as a method for injecting and injecting eyedrops into and out of eye holes, which is similar to eye drops and syringes.
To realize an actuator driven by optical stimulation using inorganic materials.
The present invention relates to a light-driven actuator configured to output mechanical motion by utilizing the phenomenon that a material is distorted in response to a light stimulus. Conventionally, in this field, actuators utilizing the phenomenon that organic materials undergo a reversible structural change by a light stimulus have been developed, but there have been problems such as slow driving speed. In the course of research focusing on inorganic dielectric materials, the inventors succeeded in thinning an oxide material as a single crystal to form a sheet. It was experimentally confirmed that the sheet deforms faster than before in response to light in the ultraviolet range, and the present invention was completed.
