... of such mechanical components allows efficient implementation of MEMS devices towards sensing and communication by tapping on to the ability of MEMS devices being displaced under external stimuli ( Basu et al., 2019b , 2019c ). Such a motion of MEMS devices can be detected both electrically and optically...

... popular. Smart homes, for example, are a new trend in the residential sector ( Alam et al., 2012 ). The definition of “Smart homes” was first suggested by Lutolf in 1992 as the “Integration of different services at home under a common communication system” ( Lutolf, 1992 ). Today, there are many...

... optics may also influence PER teaching/learning optics (e.g., research interests, content topics covered) and the dissemination of research results. Coming from a European, German speaking PER community, we have experienced national/regional and language boarders concerning the dissemination of PER...

... in optical communication. Such systems have been available since 1970s ( Stepanovsky, 2019 ) and are still used, but increasingly with integrated waveguides ( Ollier and Mottier, 1996 ). The Fabry–Perot oscillations due to reflections ( Chollet, 2016 ) from the waveguide facets can interfere...

Thus, the elements of an activity system consisted not only of the Subject, Objects, and Tools but also that this triad was part of a larger system that included the Community, Rules, and Division of Labor. It was also recognized that goals could range from learning new knowledge...
