Fleep Tech: Dose-counting Smart Label for Inhalers

Fleep Tech

The smart label is an integrated, stand-alone electronic system fully printed on plastic substrate, realized with a form factor suitable to be applied on commercially available drug-containing canisters for metered-dose inhalers.

A dose counting smart label for metered dose inhalers. The smart label, realized on a flexible substrate, integrates a fully printed OTFT based control and driving electronics as well as a fully printed battery, a touch sensor and a commercially available electrophoretic segmented display. It’s applied on the drug containing canister of metered dose inhalers: by detecting the user action when releasing the drug, it counts the remaining number of doses and provides indication of the remaining amount of drug inside the canister through the display.

Target Group

  • End users (patients requiring the use of portable drug dispensers)
  • Product and Contract Manufacturers (companies producing and/or
    commercializing drug dispensers)


Printed Electronics Components

  • Printed conductive parts
  • Printed interconnection
  • Printed sensor
  • Printed electrode
  • Printed battery
  • Printed organic TFT
  • Organic semiconductor
  • Printed dielectric/insulator

Degree of Innovation
The degree of innovation can be assessed as High. The strongest innovative feature of the demonstrator is the implementation of correctly-operating, fully printed organic flexible electronic circuitry, which opens up the implementation of electronic functionality without the need for integrating/assembling silicon chips. This electronics, based on an Organic CMOS stack, operates at voltages compatible with printed batteries: these features further strengthen the credibility of using organic printed electronics for real-life use cases, large-volumes and low-cost production schemes.

Attractiveness of Product
The product (i.e. dose-counting label for metered-dose inhalers) is a much-desired functionality for applications in the sector of biomedical packaging. Stringent requirements are nonetheless present, primarily the flexibility and ease of integration, the need not to modify the existing designs and manufacturing lines, the low total cost of production. As of now, this is not easily achievable with the conventional electronic technologies.
The demonstrator shows that well-established printed components (i.e. battery, display) can be complemented with fully-printed electronics, implementing both device-driving and computational functions, in order to deliver a fully-printed stand-alone system. This demonstration will  catalyze the interest of possible customers, expand the outreach of organic electronic technologies and contribute to substantiate the credibility of the printed electronics for real-life applications.
