Abstract: Wearable patches and wearable devices are described. The wearable patch and device include a facestock and an adhesive matrix that may be attached onto the dermis of the wearer for an extended time period.

Abstract: Acrylic polymers and pressure sensitive adhesive compositions prepared from (i) from about 1 to about 10 wt % of a carboxy functional monomer component, (ii) from about 50 to about 90 wt % of a low Tg alkyl acrylate monomer component, (iii) from about 1 to about 20 wt % of a tertiary amine functionalized alkyl acrylate monomer component, and (iv) optionally, up to 50 wt % of a vinyl ester monomer component are disclosed. The acrylic polymers and pressure sensitive adhesives are ideally suited for skin contact applications, particularly as diagnostic patches, transdermal drug-delivery patches, and dermal patches for delivery of skin actives.
