Abstract

An on-body sensor (OBS) (5610) having a continuous monitoring (CGM) device is disclosed for use in identifying an analyte, such as glucose in blood or interstitial fluid (ISF), using a biomaterial, such as glucose binding protein (GBP), that is brought into contact with the analyte. The on-body sensor (5610) incorporating the CGM device includes a housing (5625′) which provides protection to the CGM device while providing comfort to a user wearing the device. The OBS also includes an adhesive structure that provides a comfortable, discreet and secure user experience.
