care grows, intense monitoring is not
always possible.
VTT develops smooth and reliable
remote monitoring together with hospitals and health technology companies.
One common target for development is
wearable electronics. Wearable sensors
could enable remote monitoring also at
home, making it possible to send
patients home safely earlier than usual,
which would help save healthcare
resources.
" We are developing flexible smart
patches that could measure the respiration rate, oxygen saturation, heart rate,
and body temperature, for example,
and could even take an electrocardiogram (ECG). A smart patch would send
the information to a system that would
analyze the data and produce follow-up
information and send alarms. For
example, a patient recovering from surgery could move about freely while
measurements are taken, instead of
lying in a bed surrounded by wires, "
says research team leader Teemu
Alajoki of VTT.
The structure of a smart patch is
based on printed electronics that
VTT, a pioneer in the field, has
developed for about 20 years. A pliable, and even stretchable, base material moves from one roll to another, as
if in a printing press, and the circuitry
is printed on the material with conductive ink.
Separate components, such as integrated circuits, are attached to the
base with conductive adhesive, and
that can also be done automatically in
the roll-to-roll process. The largest single component on the patch is a buttoncell battery, and even that will certainly
be replaced in the coming years by a
flexible battery.
■ Data Analytics Helps Interpret
Monitoring Results
VTT is also developing data analytics
that would be capable of evaluating
changes in the various measurements
We Love A
Good Challenge
For more than 40 years, Aerotech
has solved the medical industry's
most demanding precision motion
challenges. From stent cutting, to
pacemaker welding to intraocular
lens manufacturing, our standard and
custom solutions have been used for
more medical applications than any
other precision automation company.
■ Producing Smart Patches by
Printing Electronics
Activity bracelets and heart monitor
belts are familiar examples of wearable
electronics. VTT's aim is to replace cumbersome devices with smart patches that
are nearly unnoticeable, offer excellent
comfort for the user, and can be produced in large numbers for just a few
euros apiece.

rise to your challenge.
Smart patches keep track of the patient's basic
vital functions without interruption, sending the
information wirelessly to a monitoring system.
