HOME FURNISHINGS
KEY TERMS
MEMS – three dimensional objects that
perform a mechanical function, whose
dimensions are between 1 to 100 micrometers
Nanoparticle – a particle of material at the
nanoscale
Nanotechnology – a material or structure
purposefully manufactured with dimensions
between 1 and 100 nanometers to leverage
the unique properties it has at that size
Silver ion – technically speaking, a silver ion is
an atom of silver that is missing one electron

Thermopile – a MEMS device that measures
heat

WHY NANOTECHNOLOGY?
Carpets don’t stain
Furniture doesn’t fade
Paint doesn’t chip
Windows are always clean
Surfaces are germ-free
APPLIANCES
• MEMS sensors are
increasingly being integrated
to make appliances smarter,
such as a thermopile, which
is a non-contact temperature
sensor
• MEMS thermopiles are
used in cooktops to
help regulate
temperature by
monitoring the
temperature of the pan.
When pans are
removed, the energy
transfer stops and the
burner is slightly warm

• Silver ions released
during wash/rinse cycles
• Sterilizes clothes
without hot water or
bleach
• MEMS pressure sensors
help regulate water
pressure

• A MEMS pressure
sensor is used as part of
the soil-sensing
function in dishwashers,
which determines the
appropriate amount of
water necessary to
clean the dishes. This
function can be a
significant water saver.

• Microwaves rely on a
MEMS thermopile to
monitor the
temperature of food as
it’s being cooked to
help regulate the brief
on/off cycle. It also
allows food to be

defrosted and cooked at
17
the same time.
• Refrigerators that have
automatic ice cube
makers use a MEMS
thermopile that detects
when the water is
frozen to drop the cube
into the ice bin

SHEETS
 Wrinkle Resistant
 Stain Resistant
 Repels Water
http://www.wrinklefreesheets.org/
HOUSING BUILDING MATERIALS
Concrete that repels water that results in less
stains
Coating on decking that protects the surface
from moisture, stains, scratches, and UV rays
Insulation that can be used in places besides
the attic and walls, such as around doors and
windows
• Handrails, faucets,
door knobs, and light
switches use silver ions
to remain germ-free.

FURNITURE
• Furniture has
nanotechnology-based
coatings to make it stain
resistance, fade
resistance, and scratch
resistance.

SMALL KITCHEN APPLIANCES
Non-stick coating on glass bakeware
Plastic containers have nanoparticles
embedded in them to make foods stay fresh
longer
Toasters use MEMS thermopile that measures
the temperature of the bread’s surface to
determine doneness
LIGHTING
• Light bulbs used a
MEMS-based cooling
chip that decreases the
temperature of the
bulb, which results in
lights that use less
energy, last longer, and
offer a better quality
light.
PAINTS
• Paints use a nanoguard that
makes them more water
resistant, decreasing the
chance of mildew; a harder
finish that is less prone to
chipping; exterior paints that
are dirt resistant

WINDOWS
• The use of nanoscale
materials make
windows more heat
resistant
• The nano-coating reacts
with sunlight to break
down dirt
