The mainstream types of chipless tags are digitally encoded and work at more than one millimetre range, like silicon chips. Their potential markets go beyond the lowest cost-highest volume potential markets because they have other attributes beyond cost.
or red shift. noun, Astronomy. 1. a shift toward longer wavelengths of the spectral lines emitted by a celestial object that is caused by the object moving away from the earth. Compare cosmological redshift, Doppler effect, gravitational redshift. Origin of redshift.
This phenomenon was observed as a redshift of a galaxy's spectrum, NASA wrote. This redshift appeared to be larger for faint, presumably further, galaxies. Hence, the farther a galaxy, the faster it is receding from Earth.. The galaxies are moving away from Earth because the fabric of space itself is expanding.
