All MEMS devices operate on the same
principles, but not all MEMS devices
are created equal. MEMS devices can
be broken down into two categories:
consumer-grade and industrial-grade.
An industrial-grade MEMS device is
one meant for use in extremely harsh
environments that require performance
above all else. These sensors will
sacrifice size and cost in exchange for
reliability, accuracy, and durability. The
most important requirement is low-
noise measurements. As part of this
requirement, industrial-grade devices
must meet certain qualifications, such as
AEC-Q100 for automotive applications. To
meet these standards, industrial-grade
MEMS devices tend to cost 10× that of
consumer-grade devices.
An example of an industrial application
is automation equipment on a
manufacturing line. These devices
need to operate in harsh environments
consisting of high vibration, power,
and noise. At the same time, they are
expected to achieve long lifetimes to
provide operators with the lowest total
cost of ownership possible. This kind of
application necessitates a rugged and
reliable MEMS device adhering to the
highest standards.

INDUSTRIAL GRADE MEMS

The product requirement
determines whether industrial
or commercial MEMS is needed.
Industrial grade is rated for
harsher conditions in terms of
temperature and hence have
higher costs than consumer-grade
solutions."
