not</a>. Smart watches in themselves are
probably not going to initiate changes to library
tech, but some of the new technologies in smart
watches may eventually migrate to other
technologies. For example, some smart watch makers
are preparing to use new color display technology
that requires much less power than current
power-hungry LCD displays, so their watches can
make do with smaller batteries. That kind of
technology could conceivably find its way into
self-contained low-power digital displays - like
library signage, perhaps?

I learned from researching almost every single
smart watch that has been rumored or announced</a>
(Quartz/Christopher Mims) "Qualcomm's rumored
smart watch, for example, supposedly uses
Mirasol, a kind of reflective, full-color
display that requires no power unless it's being
updated. (Mirasol displays color by refracting
light like a butterfly's wings, rather than
emitting actual red, green and blue light, like
an LCD.)"</li>

is cool: Qualcomm shows off its Mirasol
display</a> (Ars Technica/Florence Ion) "The
Mirasol display is touted for its
energy-efficiency. It offers a six-times-over
power advantage compared to both LCD and OLED
displays, which means it would be the kind of
display that a smartphone would make great use
of. It's made with a micro-electro-mechanical
system (MEMS) based on Interferometric
Modulation (IMOD) technology...."</li>

invests second $60 million in Sharp for
next-gen displays</a> (PC World/Jay Alabaster)
"Traditional LCD screens have a white back light
that sits behind an array of liquid crystal
pixels, each paired with a color filter to allow
light of a certain color to pass. MEMs screens
use a back light that cycles through a sequence
of colors, synchronized with an array of tiny
shutters that serve as pixels, flashing open
briefly to let certain colors through. The MEMS
shutters have a faster reaction time than LCD
pixels, and don't require color filters so the
back light needs less power to operate."</li>

href="http://www.digitaltrends.com/mobile/qualcomms-mirasol-display-goes-retina/">Qualcomm's
next-gen Mirasol display goes Retina</a>
(Digital Trends/Saul Berenbaum) "Most notably,
there is a silvery tint and lack of color
brightness on the screens. Some glow is also
noticeable on the edges, but the benefits are
clear. Glare is reduced and battery life is
improved by about six times, compared to the LCD
and OLED screens found on most smartphones and
tablets today. Though it's not as vivid as an
LCD screen, we could easily see it being adopted
by a number of devices, and it could open the
gates for other new types of displays."</li>

<div style="text-align: justify; font-size: 16px;
font-family: arial; line-height: 110%;">You might
get the impression from the quotes above that
micro-electro-mechanical systems (MEMS) are
specifically used for displays, but the term
applies to any electronics system built with
components that are less than 100 micrometers in
size. A micrometer is one-thousandth of a
millimeter, and at these extremely small sizes,
the standard rules of classical physics do not
always apply.
