“There is an epidemic of allergic
disease in Europe and elsewhere
in the world.”
Peter Burney, Vice President of research at the
Global Allergy and Asthma European Network
(GALEN)
Aristotle University of Thessaloniki

Department of Electrical and Computer Engineering
Target Group:
20% of the world population suffers from
allergic diseases
Asthma is caused by allergies in 50% of adults
and at least 80% of affected children.
150 million people worldwide suffer from
asthma
1 out of 3 European citizens suffer from some
allergy related condition

Design Considerations
Non intrusive, transparent system,
easy to use and understand.
Allergens move constantly because of
wind currents.
People have different sensitivities to
the various allergens.
There are people with allergies in
food and medicine.
Aristotle University of Thessaloniki
Faculty of Engineering
Department of Electrical and Computer Engineering
Measures the concentration of allergens in the
air.
Interprets the measurements according to the
user’s sensitivity.
Computes the risk factor for an allergic
reaction.
Warns the user of rising risk to his health.
Offers assistance to people with allergies in
food or medicine.

Why is the system innovative?
The only mobile system that combines
airborne-allergens and allergies in food
and medicine
Personalized, real time risk assessment
(in contrast with generic, once-a-day
pollen count information)
The only application of e-nose sensors
on allergen detection
Aristotle University of Thessaloniki
Faculty of Engineering
Department of Electrical and Computer Engineering
Why is the system effective?
Easy-to-use
Not a source of annoyance
On-the-spot advice
Compact-size, low-weight sensor module
Aristotle University of Thessaloniki
Faculty of Engineering
Department of Electrical and Computer Engineering
Why is the system effective?
(larger scale effects)
Enhances social life of allergic people
By preventing allergic seizures:
Minimal hospitalization
Reduced medication
Substantial savings in health resources
16.7 million office visits to health care providers in the USA
11.3 billion $ annual cost for asthma treatment in the USA
Aristotle University of Thessaloniki
Faculty of Engineering
Department of Electrical and Computer Engineering
How does the system adapt to the
user?
Risk assessment according to user’s
sensitivities
Food and drug advice according to the
user’s allergen specifications
The system is aware of the user’s location
and provides location specific information
