metered dose Inhaler

Carclo Technical Plastics have developed a technology to inkjet-print flexible electronic circuits. They commissioned eg technology to develop their first medical device using this technology. 

THE project

eg technology developed a wireless-enabled, metered-dose inhaler, with Carclo’s flexible circuit technology combining sensing, a printed antennae and the mounting of small and large electronic components in a 3D form. 


The product implements a Texas Instruments Bluetooth Low-Energy (BLE) chip including a printed antenna and printed battery contacts. The MDI detects actuation of the dose canister and records a timestamp which can be downloaded over a wireless data link at the clinic. This connected technology addresses the complex problem of monitoring compliance, providing confirmation of dosing times.
