ENCAPSULATED WEARABLE DEVICE AND SYSTEM WITH INCREASED SURFACE ENERGY
Aspects of the present disclosure include a polymer matrix that is formed on a wearable device to increase the surface energy and reduce the tackiness of the surface of the wearable device. The present disclose includes a wearable device that can be worn on a user, such as one the user's skin. The device includes one or more electronic components and an encapsulation layer surrounding the one or more electronic components. The device further includes a polymer matrix at least partially covering a first side of the wearable device. The polymer matrix has a higher surface energy than the encapsulation layer so as to improve adhesion with an adhesive layer. The present disclosure also includes a wearable device system that further includes the adhesive layer.
