In wearable microneedle systems, accuracy depends on more than sensor chemistry. It also depends on how the device is applied, adjusted, and secured on the body. One of ZP’s patented innovations, WO 2021/205110, addresses this often-overlooked challenge and forms an important layer of ZP’s wearable microneedle IP moat.
This patent covers a specialised adhesive patch system designed to work seamlessly with removable microneedle capsules. Unlike conventional patches that are applied in a single irreversible step, this design allows users to position and adjust the wearable comfortably before the microneedles ever touch the skin. A multi-part peel-away liner protects both the adhesive and the microneedles during placement, enabling precise alignment on the wrist or limb before activation.
At the centre of the patch is an opening that securely receives a microneedle capsule while leaving the surrounding adhesive free to stabilise the device. Thoughtful design details—such as split peel tabs, ergonomic shapes, breathable materials, and skin-friendly contours—reduce discomfort, limit hair pull, and maintain adhesion during daily movement. The result is a system that supports long-term wear without compromising microneedle integrity or user comfort.
Within ZP’s broader portfolio, this patent complements IP covering microneedle geometry, insertion verification, sensing chemistry, modular capsules, repositioning, and continuous wear. Together, these inventions protect not just how biomarkers are measured, but how wearable microneedle devices are applied correctly and trusted in real-world use.
For partners collaborating with ZP, this patent represents more than an adhesive solution. It is part of a system-level IP moat that de-risks wearable microneedle products at a critical interface between user and technology—ensuring that advanced sensing can be delivered reliably, comfortably, and at scale.
