At Zimmer & Peacock, our wearable microneedle portfolio continues to push the boundaries of non-invasive biochemical monitoring. One key innovation, captured in WO 2020/025818, addresses a subtle but critical challenge: sweat interference.
This patent introduces a microneedle design where the tip is fully metal-coated and biochemically functionalized for sensing, while the base features only a carefully controlled metal surface—just 1–20% of its total area. This simple but powerful adjustment ensures reliable signal transmission from interstitial fluid while minimizing noise caused by sweat on the skin.
Beyond signal precision, the design integrates into a modular, replaceable capsule system, enabling reusable electronics and long-term, low-risk monitoring. By combining material science, electrochemistry, and wearable design, this invention reinforces ZP’s growing IP moat in continuous, minimally invasive monitoring.
In short, this patent exemplifies how smart microengineering and biochemical control underpin ZP’s leadership in wearable sensing technology.
