By using the device on a patient, a physician is provided with an accurate way to perform a respiratory and heart health assessment of the patient during a telehealth visit.

A heart monitoring system (100) comprises an array of force-sensitive resistors (10) spanning a sensor surface (50). Each resistor (10) is configured to change a respective resistance value (R) in accordance with an amount of static pressure (P) exerted on the sensor surface (50) at a respective location of the force-sensitive resistor (10) by a subject (200). An array of piezoelectric transducers (20) is interspersed among the array of force-sensitive resistors (10). Each transducer (20) is configured to generate 10 a respective time-dependent electrical signal (S) in accordance with respective vibrations (F) exerted on the sensor surface (50) at a respective location of the transducer (20) by the subject (200). A controller (30) is configured to determine a heart rate (H1) of the subject (200) based on a combination of the measured resistance values (R) of the force-sensitive 15 resistors (10) and the time-dependent electrical signals (S) of the piezoelectric transducers (20).

An embodiment of the present invention provides a sphygmomanometer that is worn on a measured part of the left wrist of a subject (user) for use. In the sphygmomanometer, on an inner peripheral surface of a band-like body that constitutes a base of a band, a portion for installing a pressure cuff and a protrusion for installing an antenna substrate are separately provided, and the pressure cuff and the antenna substrate are respectively installed on these portions.

System for determining real-world effectiveness of various prescribed medications. Here a variety of different types of patient pulse wave measurements (e.g. blood pressure, pulse oximeter, ECG) and other physiological measurements are obtained. This actual data is compared to calculated measurements that would be expected based on the various patient baseline measurements in the absence of medication, schedule of medications, and impact of medications the various patient baseline measurements. If the actual data meets expectations, then the medication is likely acting as anticipated. Depending on which types of data do not meet expectations, problems with one or more previously described medications may be reported. Other types of patient physiological readings, such as temperature, motion, lung function, brain wave function (EEG) and the like may also be obtained, and these additional types of readings can be used to extend the range of different types of drugs/medications that the system can successfully monitor.

The invention refers to an implantable sensing system comprising an electronic implant and a reading unit to obtain measurements originating at the implant or its surroundings to characterize physical and/or chemical clinical parameters of a living body. The electronic implant comprises an electronic circuit and at least two electrodes connected to the electronic circuit. The electronic circuit comprises a capacitor and a device of asymmetric conductance capable of rectifying an alternating current, both connected in series between two electrodes. An electronic component is connected in parallel with the device of asymmetric conductance, for the capacitor discharge. The capacitor, the device of asymmetric conductance and/or the electronic component, can be a transducer selected such as an operational parameter of the transducer is variable depending on a physical and/or chemical condition of a medium of a living body. The implant features a minimal invasiveness, such as it can be implanted by injection or by catheterization rather than by open surgery.

A vital information measuring apparatus according to an aspect of the present invention is a vital information measuring apparatus for measuring vital information by compressing a measurement site of a subject with a cuff, and includes a fluid supply unit configured to supply a fluid to the cuff, and a first fluid supply controller configured to control, when a situation of the subject satisfies a first condition in which measurement of the vital information is recommended, a supply of the fluid to the cuff by the fluid supply unit to compress the measurement site in a first compression mode for informing the subject that the first condition is satisfied.

The described systems and methods determine a driver's fitness to safely operate a moving vehicle based at least in part upon observed UVB exposure patterns, where the driver's UVB exposure levels may serve as a proxy for vitamin D levels in that driver's body. A smart ring, wearable on a user's finger, continuously monitors user's exposure to UVB light. This UVB exposure data, representing UVB exposure patterns, can be utilized, in combination with driving data, to train a machine learning model, which will predict the user's level of risk exposure based at least in part upon observed UVB exposure patterns. The user can be warned of this risk to prevent them from driving or to encourage them to get more sunlight exposure before driving. In some instances, the disclosed smart ring system may interact with the user's vehicle to prevent it from starting while exposed to high risk due to deteriorated psychological or physiological conditions stemming from insufficient UVB exposure.
