KERMIT

KERMIT aims to create a new generation of non-invasive diagnostic tools for kidney disease by using sweat as an accessible biofluid. Instead of relying on conventional blood or urine testing, the project explores how wearable technologies can support earlier screening, easier follow-up and more patient friendly testing.

The main objectives are:

• Develop printed electrochemical sensors for kidney disease related biomarkers, including creatinine, cystatin C and urea.
• Integrate sweat stimulation using screen printed iontophoresis electrodes and transdermal cholinergic agents
• Route sweat through a thin microfluidic layer toward dedicated sensing areas.
• Combine the sensing system with low power electronics, an antenna and smartphone-based readout.
• Validate the patch concept using clinically relevant samples and patient testing workflows.
• Improve the sustainability of wearable medical devices through bio-based recyclable or lower impact materials.
• Establish a device architecture that can support future point of care and remote health applications.

In simple terms, KERMIT is trying to answer a very practical question: can we make kidney function testing easier, softer and closer to the patient?
