“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 ThessalonikiFaculty of EngineeringDepartment 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

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.
Design Considerations
Aristotle University of ThessalonikiFaculty of EngineeringDepartment 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.

Advice to drug allergic people
Aristotle University of ThessalonikiFaculty of EngineeringDepartment of Electrical and Computer Engineering
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 ThessalonikiFaculty of EngineeringDepartment 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 ThessalonikiFaculty of EngineeringDepartment 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
