Hand-Held Nebulizer Design with Secure Authentication Capability

Designed Using a PIC16F1718 MCU and an ATSHA204 CryptoAuthentication™ IC

Our Hand-Held Nebulizer Design with Secure Authentication Capability Demonstration shows a functional nebulizer design where only the manufacturer’s medicine cup will authenticate with the same manufacturer’s main nebulizer head unit and not with a counterfeit medicine cup. The benefits of authentication are protection for brand name, brand quality, sales revenue, service revenue and from regulatory and legal liability issues.

Nebulizer Development Made Easy

We provide downloadable design files, including schematics, ‘C’ source code and an application note, which can easily be modified to your specific nebulizer application needs. These design files help you develop accessory authentication functionality for nebulizers and other drug delivery devices*. We also offer the hardware you’ll need to start prototyping. Below are devices that we recommend using in your nebulizer design, all of which meet our strict quality standards and come with comprehensive support, all from the same supplier.
