Smart polymers, stimuli-responsive polymers or functional polymers are high-performance polymers that change according to the environment they are in. . Such materials can be sensitive to a number of factors, such as temperature, humidity, pH, chemical compounds, the wavelength or intensity of light or an electrical or magnetic field and can respond in various ways, such as altering color or ...
Smart materials, also called intelligent or responsive materials, [1] [page needed] are designed materials that have one or more properties that can be significantly changed in a controlled fashion by external stimuli, such as stress, moisture, electric or magnetic fields, light, temperature, pH, or chemical compounds.
Untethered actuation is achievable, especially in soft robots with liquid crystal polymers, a category of stimuli-responsive materials with two way shape memory effect. This can allow the liquid crystal polymers to generate mechanical energy by changing shape in response to external stimuli, hence untethered actuation.
These crystallites form covalent netpoints which prevent the polymer from reforming its usual coiled structure. The hard to soft segment ratio is often between 5/95 and 95/5, but ideally this ratio is between 20/80 and 80/20. [12] The shape-memory polymers are effectively viscoelastic and many models and analysis methods exist.
In other words, assistive technology is any object or system that helps people with disabilities, while adaptive technology is specifically designed for disabled people. [7] Consequently, adaptive technology is a subset of assistive technology. Adaptive technology often refers specifically to electronic and information technology access. [8]
iOS 11 was introduced at the Apple Worldwide Developers Conference keynote address on June 5, 2017. [3] [4] [5] The first developer beta version was released after the keynote presentation, [6] with the first public beta released on June 26, 2017. [7] iOS 11 was officially released by Apple on September 19, 2017. [8] It brought many changes to iOS.
Adaptive learning, also known as adaptive teaching, is an educational method which uses computer algorithms as well as artificial intelligence to orchestrate the interaction with the learner and deliver customized resources and learning activities to address the unique needs of each learner. [1]
