The patch is designed as a multilayered system. The outermost layer consists of a flexible, breathable medical-grade polyurethane film that serves as a waterproof and microbial-resistant barrier. Below this lies a sensor interface sheet constructed using Tegaderm film, pre-coated with a thin layer of biocompatible gel to ensure non-irritant contact with neonatal skin. The entire device weighs under 15 grams and has a thickness of <3mm, ensuring no pressure is exerted on cranial sutures or the soft fontanelle region. The patch uses a hook-snap mechanism integrated with a stretchable medical-grade silicone band for secure, yet gentle adhesion, allowing 24x7 attachment without frequent reapplication.
