Abstract: A self-cleaning face covering is provided. The face covering includes a fabric layer having a resisitive heating element disposed on the fabric; and an infrared reflective layer arranged between the fabric layer and an inner surface of the face covering configured to reduce heat transfer to the inner surface. Methods of cleaning the face covering are also provided.

Abstract: A passive sensing continuous glucose monitoring system and method of use thereof. The system includes a passive antenna formed of biocompatible silicon carbide (SiC), modeled to a desired frequency, which is permanently implanted subcutaneously. The system further includes an external-to-the-body transmitting antenna to detect changes in the blood glucose level by sending a radio signal at the frequency of the implanted passive antenna into the body. This signal is received and reflected by the passive antenna, and the reflected signal is then received at an external-to-the-body receiving antenna. Changes in the glucose level lead to modifications in the signal and can be used to determine the blood glucose level externally.

Abstract: In one embodiment, an implantable biosensor includes a sense antenna comprising a silicon carbide substrate and a radiating electrode formed on the substrate.

Abstract: A wearable monitoring device is provided to detect the physiological condition of a user and alert emergency services if needed. As provided herein, the monitoring device may include a band configured to be worn on a user's wrist; two or more operably connected PPG sensors arranged on the band, wherein at least two of the two or more PPG sensors are arranged such that the sensors contact opposite sides of the user's wrist when the device is being worn and wherein the at least two PPG sensors provide a higher signal to noise ratio as compared to a single PPG sensor; and a processor configured to receive and process readings from the at least two PPG sensors. Methods of using the monitoring device are also provided.
