Electrofluidic paper sensing
Laser-patterned paper electrodes, read electrochemically. From research at ETH Zurich.
A CO₂ laser draws the electrode pattern onto paper. The sample wicks across the electrodes; the reaction produces a current; the current is the reading.
A number, not a colour change. It can be timestamped, transmitted and trended.
Remote data acquisition
Scheduling, connectivity and device health. With Xube.
Each instrument reports its readings and its own state: films remaining, power, link quality.
Schedules are set remotely. A reading can be triggered on demand.
Unattended operation
A magazine of up to 1,000 sensor films. Site visits are to replace the magazine.
Water flows through the cartridge automatically. Each reading uses one film.
Magazine size and reading frequency set the interval between visits.
