Abstract: An adhesive device may include a first adhesive surface configured to be adhered to skin of a user, and a second adhesive surface opposite the first adhesive surface and configured to be adhered to a medical device. The adhesive device may also include an intermediate region between the first adhesive surface and the second adhesive surface, where the intermediate region includes a detector compound embedded in the intermediate region configured to change based on interaction of the detector compound with a target molecule.

Abstract: Some embodiments relate to ear-mountable devices with one or more sensors and both input and output capabilities. Such ear-mountable devices may validate behaviors, biometrics, and/or environmental conditions by generating a signal indicative of the same at an ear of the user and then determining the behaviors, biometrics, and/or environmental conditions based on the signal. Such ear-mountable devices may determine compliance of a user by outputting, through an audio output device of the ear-mountable devices, a compliance message to evoke a target behavior in the user, monitoring behavior of the user through a sensor of the ear-mountable device, and determining compliance of the user with the target behavior based on the monitoring.
