Two modules
An electronic unit and a fluidic cell.
Our design separates the device into two distinct yet interconnected modules: a main electronic unit and a fluidic cell module. The main electronic unit, in a robust yet lightweight nylon case, is the heart of the device — ensuring precise measurements and optimal performance, with an interface simple to operate even for those new to the technology.
The Sensor Module, on the other hand, is designed for versatility and adaptability. Encased in a durable casing, it withstands a range of working conditions and is designed for ease of maintenance and cleaning.
- In this view
- Fluidic top cover with the window and its O-ring
- Lever: fine regulation of the O-ring pressure
- Proximity board: pogo pins and MCP9808 temperature sensor
- Main electronics: network analyser shield and Teensy
- Nylon PA2200 case, eight SLS-printed parts
Sensor module
Mount it with a single, swift gesture.
- OpenRemove the fluidic top cover.
- PlaceLay the crystal with its back electrodes on the pogo pins.
- CloseInsert the cover with the lever on “min”, then turn the lever to seal.
- CheckDraw water towards the cell with a syringe and stop before it enters: a still level means a tight seal.
