Designing Adhesives for Wearable Applications


Adhesives selected for affixing wearable medical devices to skin should exhibit four major properties to ensure product efficacy: 1) High cohesive strength, or shear resistance, to prevent device movement. 2) High levels of initial tack to quickly adhere the device to skin. 3) Provide high MVTR to ensure breathability, prevent the accumulation of moisture under the adhesive and maximize adhesive strength, and 4) Withstand gamma, E-beam or EtO sterilization.
