A breath detection apparatus for monitoring individual breaths of a patient. The apparatus includes a sensing assembly comprising a humidity sensor. The sensing assembly adapted to be connected to an oxygenation device wherein respiratory gases of a patient are directed over the sensing assembly and the humidity sensor is adapted to monitor differences in humidity during a breath of the patient. The humidity sensor generates an electrical signal representing a humidity level in response to measuring the humidity during the breath. The apparatus also includes a processor in electrical communication with the sensing assembly to receive electrical signals generated by the humidity sensor and determine a state of the relative humidity during the breath, and a visual display element controlled by the processor and adapted to display a predetermined visual alert in response to the state of the relative humidity during the breath.

A modular deformable electronics platform is attachable to a deformable surface, such as skin. The platform is tolerant to surface deformation and motion, can flex in and out of a plane of the platform without hindering operability of electrical components included on the platform, and is formed via arrangement of discrete flexible tiles, with corners of adjacent tiles connected by a flexible connection material so that individual tiles can translate and rotate relative to each other. Interconnects disposed on bases of separate tiles electrically connect adjacent tiles via their connected corners, and electrically connect components disposed on different tiles. Each pair of adjacent corner connections defines an axis about which at least a portion of the platform can flex without deformation and without hindering connections between tiles. The flexible material and/or bases of the tiles can include Parylene.

A wireless sensor platform design and a single walled carbon nanotube/ionic liquid-based chemidosimeter system can incorporated into a highly sensitive and selective chemical hazard badge that can dosimetrically detect an analyte down to a sub parts-per-million concentration.

A system for monitoring medical conditions including pressure ulcers, pressure-induced ischemia and related medical conditions comprises at least one sensor adapted to detect one or more patient characteristic including at least position, orientation, temperature, acceleration, moisture, resistance, stress, heart rate, respiration rate, and blood oxygenation, a host for processing the data received from the sensors together with historical patient data to develop an assessment of patient condition and suggested course of treatment, including either suspending or adjusting turn schedule based on various types of patient movement. Compliance with Head-of-Bed protocols can also be performed based on actual patient position instead of being inferred from bed elevation angle. The sensor can include bi-axial or tri-axial accelerometers, as well as resistive, inductive, capacitive, magnetic and other sensing devices, depending on whether the sensor is located on the patient or the support surface, and for what purpose.

Methods and apparatus provide monitoring of coughing and/or a sleep disordered breathing state of a person. One or more sensors may be configured for non-contact active and/or passive sensing. The processor(s) may extract respiratory effort signal(s) from one or more motion signals generated by active non-contact sensing with the sensor(s). The processor(s) may extract one or more energy band signals from an acoustic audio signal generated by passive non-contact sensing with the sensor(s). The processor(s) may assess the energy band signal(s) and/or the respiratory efforts signal(s) to generate intensity signal(s) representing sleep disorder breathing modulation. The processor(s) may classify feature(s) derived from the one or more intensity signals to generate measure(s) of coughing and/or sleep disordered breathing. The processor may evaluate sensing signal(s) to generate indication(s) of cough event(s) and/or cough type which may include generating an indication of a coronavirus disease or a coronavirus disease cough type.

In an example, the technique also detects and measures vital signs of each human target by continuous, non-intrusive method. In an example, the vital signs of interest include a heart rate and a respiratory rate, which can provide valuable information about the human's wellness. Additionally, the heart rate and respiratory rate can also be used to identify a particular person, if more than two target humans living in a home. Of course, there can be other variations, modifications, and alternatives.

A moisture-sensitive device is provided that includes a dissolvable conductive material. Exposure of the dissolvable conductive material to urine or some other fluid causes the dissolvable conductive material to dissolve, increasing an effective resistance of the dissolvable conductive material. This change in resistance can be detected to determine the presence of an aqueous fluid. In response to such detection, a transmitter can then provide a wireless transmission indicative of the presence of the fluid. This moisture-sensitive device can be provided in a diaper and transmissions produced by the device can be detected using a smart phone or other device and used to indicate to a user that the diaper has been soiled.

A system is described to create customized unique identification (UID) codes combined with customized printable optical or NFC sensors and to combine these unique sensors and unique IDs with unique environmental events, traceability, unique data from cell phones (including geolocation) and person-specific unique indicators such as biomarkers to create completely unique, low cost and proprietary printable genomic and environmental blockchain sensor networks for the Internet of Things (IoT), counterfeit identification, healthcare, pharmaceutical applications and small payment transactions worldwide.
