An internal wear study assesses the functionality of a new device and may reveal a design issue in terms of wearability, skin irritation, or adhesive performance, which can be addressed by conducting further wear studies or refining the material selection.

At the "Internal Wear Study" stage of product development for a medical wearable device, the focus is on conducting monitored wearability tests and internal reviews to assess the performance of the device under real-world conditions. These studies evaluate the device's adhesive materials, design, and overall functionality through controlled internal trials and gathering data on how the device adheres to the skin, its durability over the intended wear period, and user comfort.

Feedback collected during this stage is crucial for identifying any issues with wearability, skin irritation, adhesive performance, user interface, and device functionality. This feedback can shape the direction for further wear studies or finalizing the material selection. Avery Dennison Medical’s experts have experience running wear studies and can support this phase of the project.
