A nano-tensile tester for creep studies
Free-standing metallic thin films are increasingly used as structural components in MEMS. In commercial devices, long-term reliability is essential, which requires determining time-dependent mechanical properties of these films. The uniaxial tensile test is a preferred method due to uncomplicated determination of the stress and strain state. However, at the MEMS-scale this method is not straigh...
متن کاملThe electronic visual acuity tester: testability in preschool children.
PURPOSE To evaluate the ability of preschool children to have their threshold visual acuity assessed using a standardized, computer-based letter test. METHODS Participants were 1195 3.5- to 5-year-old children enrolled in the Vision in Preschoolers Study. Monocular visual acuity was assessed by licensed eye care professionals (optometrists and pediatric ophthalmologists experimented in the ex...
متن کاملEvaluation of a sugar-based edible adhesive using a tensile strength tester.
A method to evaluate adhesives has been developed and used to reformulate a recently patented adhesive which is based on sugar and citric acid. Factors affecting adhesive performance were uncovered, such as an optimal curing temperature of 60°C. The addition of maltodextrin and soy protein at optimized levels was shown to nearly double the bonding strength of the adhesive, from 0.46 ± 0.076 to ...
متن کاملA monolithic micro-tensile tester fabricated by femtosecond laser to inves- tigate fused silica mechanical properties
We present an experimental method to fill in the existing gap of characterization tools for the mechanical testing of fused silica and silica’s polymorphic phases in the microand nanoscales. The approach is based on a monolithic tensile tester, entirely made of fused silica for which the same femtosecond laser in not only used for the fabrication of the device, but also for its operation (loadi...
متن کاملTemperature controlled tensile testing of individual nanowires.
We present a novel experimental method for quantitatively characterizing the temperature-dependent mechanical behavior of individual nanostructures during uniaxial straining. By combining a microelectromechanical tensile testing device with a low thermal mass and digital image correlation providing nm-level displacement resolution, we show successful incorporation of a testing platform in a vac...
