Abstract: The present disclosure relates to a human body temperature sensor fabricated through inkjet material printer at room temperature in two steps deposition process. The proposed sensor consists of silver based interdigital electrode and carbon black film as sensing elements, which are sensitive towards human body temperature. In various embodiments, the present disclosure has two terminals that provide change in resistance against temperature detection. The change in resistance is directly proportional to the change in temperature i.e. positive temperature coefficient (PTC). Interdigital electrodes (IDE) fingers spacing were optimized for the high sensitivity and linear resistance behavior at a temperature range is recorded. The sensor response is very linear on the human body temperature readings.
In embodiments, a polyimide PI substrate in combination with Polydimethylsiloxane (PDMS) encapsulation layer is utilized in the device fabrication. The thermal sensing property of the carbon black film and PI substrate is exploited to detect human body temperature.
In embodiments, mass production of the sensor at very low cost can be done with screen printing technique in 3 steps. 1) Patterning of silver IDE, 2) deposition of carbon sensing film, and 3) PDMS encapsulating layer. The proposed sensor can be scaled according to the requirement from μm to cm size.

Abstract: A facial mask configured to be worn by a user includes a mask substrate, a temperature and respiration rate sensor for monitoring the temperature and breathing rate of the user, a humidity sensor for monitoring the humidity of the breath of the user, and a cough sensor for monitoring the cough rate of the user. The sensors may be printed onto a sensor array substrate, which is then secured to the mask substrate. The sensors provide real-time monitoring of the temperature, the breathing rate, the humidity, and the cough rate of the user.

Abstract: A wearable sensor for real-time human body temperature measurement is provided. The wearable sensor includes a substrate, a first electrode on the substrate, a second electrode on the substrate, the second electrode being spaced apart from the first electrode, and a sensing film on the substrate. The sensing film is electrically and/or spatially disposed between the first electrode and the second electrode. A resistance between the first electrode and the second electrode changes in response to a change in temperature surrounding the sensing film.
