“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)


  • Target Group: elsewhere in the world.”

  • 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


  • Measures the understand.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.


How this technology helps us understand.

Live Healthier Lives

  • So preventing allergic crisis helps people live healthier lives

  • Heart palpitations

  • Hives

  • Impaired sense of smell

  • Vomiting

  • Watery, itchy, crusty or red eyes

  • Dark circles under or around the eyes

  • Dermititis

  • Depression

  • Absentmindedness

  • Anaphylaxis

  • Asthma

  • Joint aches

  • Muscle pains

  • Nasal congestion

  • Sneezing

  • Swelling (angioedema)

  • Throat hoarseness

  • Rapid pulse

  • Rhinorrhea (runny nose)

  • Ringing, popping or fullness in the ears

  • Dizziness

  • Eczema

  • Embarrassment

  • Vomiting

  • Watery, itchy, crusty or red eyes

  • Shortness of breath

  • Skin Rashes

  • Sleep difficulties

  • Shortness of breath

  • Skin Rashes

  • Sleep difficulties

  • Nasal polyps

  • Nausea

  • Postnasal drainage (postnasal drip)

  • Burning eyes

  • Constipation

  • Coughing

  • Irritability/behavioral problems

Pocket and Desktop PC Application


Pocket PC add-on understand.

Custom made device used to acquire andtransmit the essential data for allergen identification and concentration measurement

Measurements are performed by an electronic-nose sensor

The resulting signals are digitized, filtered andamplified by an ADuC834 microprocessor

Data are sent to the AllergyON! Pocket PC application via RS232 interface.

  • Food ingredients database

  • Drug ingredients database

  • IIS 5.0 Web Server

  • Web Services for the exchange of the data between client (Pocket PC) - server

  • Sites for registration, system browsing, help


Web Services understand.

  • Help food allergic people by:

    • Obtaining food ingredients data, based on specified food name

    • Providing international cuisine info, helping users who travel

    • Allowing for restaurant menu download

  • Help drug allergic people by displaying substances contained in any specified drug

  • Access to weather and pollen forecast data


  • Scenario #1: A walk in the open…

  • Data acquisition simulation

  • Risk level change and user warning

  • Data graphs and maps

System Demonstration


Why is the system innovative? understand.

  • 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


Why is the system effective? understand.

  • Easy-to-use

  • Not a source of annoyance

  • On-the-spot advice

  • Compact-size, low-weight sensor module


Why is the system effective? understand.(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


How does the system adapt to the user? understand.

  • 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
