IoT solution for precise and non-destructive moisture monitoring

Manufacturing of an IoT moisture sensor in partnership with InviSense. The Swedish company InviSense makes being a facility owner easier with accurate and convenient measurements of the humidity in building constructions.

The need for a production partner with in-house production and well managed quality and process control layed the foundation for the partnership between InviSense and Mekoprint.

The Swedish company InviSense develops and sells extremely thin passive moisture sensors which, built in to walls, floors or roofs, measures relative humidity in buildings without damaging the construction.

With a 0.1 mm thin passive moisture sensor and InviSense cloud based service, facility owners are able to measure in real time, analyse and secure the humidity. An IoT solution where all measurement data is saved and connected to each sensor.

Globally competitive production

InviSense chose Mekoprint as their prodution partner as they had a specific need for process control. The production setup should be globally competitive focusing on cost optimization. Also all processes should be highly controlled, both tolerances in each process as well as the alignment between processes.

A minimal of manual handling is involved in the production of the sensor. With a roll-to-roll production setup Mekoprint is able to control process parameters and quality standards to the degree needed by InviSense. Because documentation and complete reproducibility is extremely important and essential for the functionality and commercial succes of the sensor, this had key priority and importance when choosing production partner.

Sensor design

The sensor consists of etched cobber foil with silk screen printed electrically conductive circuits of silver and parts of lacquer and transfer tape. As a finishing process the printed sensor is punched into right dimensions. and delivered to InviSense as ready-made items. Packed and ready for application.

"We had two primary reasons for choosing Mekoprint as our production partner. A well managed quality and process control together with complete in-house production setup for printing, etching and finishing, Mekoprint are able to handle all processes in the production."
