Micro electro-mechanical system (or
MEMS) technology has been with
us for several decades, but in terms
of its true potential some would
argue that it has barely arrived. The
integration of electrical circuits and
mechanical structures on a single
substrate, at the micron scale, is the
enabling technology behind most
wearable devices and fundamental
to many smartphone functions.
MEMS is also having a massive
impact on the development of
biotechnology, providing researchers
the ability to search for, locate and
influence biological and chemical
compounds in the body and its
many complex subsystems. This
will undoubtedly lead to new ways
to identify and prevent illnesses and
debilitating conditions. For example,
can be used to reduce the size of
equipment, making it more portable,
while their relatively low cost means
the prospect of disposable sensors
becomes feasible. The scope of their
use includes measuring the blood
pressure and respiration of patients
in hospitals and ambulances. Their
application in dialysis machines
and infusion pumps has also been
ground breaking.
The incorporation of MEMS inertial
sensors in consumer devices is also
influencing the way health providers
are addressing the care of vulnerable
patients who may be susceptible
to falls. Monitoring the movement
of patients can provide an early
warning system for carers, alerting
them to the need for attention.
The same technology is now being

the use of MEMS technology in nerve
prosthesis is now being explored,
research that could help the blind
see or return some mobility to the
disabled - clearly real life enhancing
developments.
MEMS has been a disruptive
innovation within the medical
sector for diagnosis and health
care, and been very successfully
applied in pressure sensors. Today
MEMS-based pressure sensors
that communicate using RF can be
implanted into the body, providing
a valuable insight into the condition
of organs and arteries. Recent
advancements in the packaging of
MEMS has been instrumental here.
Outside of the body, the small and
unobtrusive form factor of MEMS
pressure sensors means that they
