Panaseer Passive Allergen Detection


EpiPen’s are the most common anti-allergen medical device. Despite this, they are often not carried at all, not used properly or used too late in the instance of a reaction, because they are inconvenient to carry and so rarely required.


The lines between necessity and desirability are becoming increasingly blurred with healthcare technology. Feeling restricted or self-conscious about a product can lead to a lack of interest, even if it is potentially life-threatening.


A convenient, preventative, desire-driven approach to allergy management can save both time and lives.

Organic Sensing Technology

The Hertzstueck near-infrared sensor, developed by trinamiX, allows for infrared spectrometry analysis to be packaged into a very small form factor. This technology can be used to developed a handheld or wearable food-scanner, which could alert users the presence of allergens before they come into contact with them.

User Journey

Stacks Image 38

User enters Pret A Manger, proudly wearing her newly acquired Panaseer.

Stacks Image 41

She reaches for a sandwich, too hungry to stop and check the label thoroughly.

Stacks Image 145

Feeling a vibration on her wrist, she looks down, alarmed to see the LEDs flashing.

Stacks Image 47

She opens the app on her phone and sees the Panaseer detected traces of sesame, relieved at having avoided eating the sandwich.

Stacks Image 50

She removes the module from the wristband and actively scans the next sandwich, feeling empowered.

Stacks Image 53

Her parents, notified that the via the companion app, receive a text from her telling them she is fine and are relieved.

Digital Prototyping

Stacks Image 77

Selection of allergens to detect. Groups of users could select allergens for each other as well to increase the effective scanning area.

Stacks Image 80

Scan history allows user to build a profile of how they’ve used their Panaseer.

Stacks Image 83

The user can alert their guardian when an allergen is detected in case they need immediate assistance.

Stacks Image 85

Guardians receive a notification when the user sends them an alert. They are able to track the user’s location and provide assistance.

For allergy sufferers, there is a difficult balance between tedious caution on the one hand and subtle recklessness on the other. Panaseer offers a third hand: protected autonomy.
