Abstract: A method of depositing of a film on a substrate with controlled adhesion. The method comprises depositing the film including metal, wherein the metal is deposited on the substrate using physical vapor deposition at a pressure that achieves a pre-determined adhesion of the film to the substrate. The pre-determined adhesion allows processing of the film into a device while the film is adhered to the substrate but also allows removal of the device from the substrate.

Abstract: A medical sensor device includes a sensor assembly including an underside surface for attachment against a patient's skin, a sensor portion to detect a characteristic of the patient, and sensor assembly contacts which in operation carry signals representing the detected characteristic. The device also includes a transmitter assembly removably engageable with the sensor assembly and including circuitry to take the signals from the sensor assembly contacts and to transmit readings of the detected characteristic to external equipment. The device also includes mechanical interface components on the sensor assembly and the transmitter assembly which allow the transmitter assembly to be brought into abutment with the sensor assembly at a first angular position via relative axial movement between them, and then allow a relative rotation of the assemblies with respect to one another towards a second angular position and presents axial separation of the assemblies in the second angular position.

Abstract: A glucose biosensor encasement includes a first membrane and a second membrane. The first membrane has a first interlocking segment. The second membrane has a second interlocking segment cooperating with the first interlocking segment of the first membrane to provide a cavity between the first membrane and the second membrane configured to receive a glucose sensor. At least one of the first membrane and the second membrane comprises a semi-permeable portion configured to regulate diffusion characteristics of glucose through the membrane to realize a sensitivity for a sensor in the cavity. A method is also provided.

Abstract: Methods, systems, and devices for continuous glucose monitoring. More particularly, the methods, systems, and devices describe a working electrode with a GOx sensor and a background electrode in which the background electrode has no GOx sensor. The system may then compare the first signal and the second signal to detect ingestion of a medication by the user. The system may generate a sensor glucose value based on the comparison.
