The present disclosure discloses a wearable device for measuring physiological parameters of a subject while being worn. The device includes one or more sensors that perform the measurement of the physiological parameters. The sensors can be selected from either a light-based sensor or displacement sensor. The device includes a skin contact member that has a skin contact surface facing an external side of the device that faces the skin of the subject. During measurements of one of the sensors, the contact surface engages the skin of the subject to allow performing measurements by at least one sensor. The light-based sensor is configured to perform the measurement via the skin contact surface, and the displacement sensor is configured to sense the displacement of the skin contact surface. For allowing accurate performance of the measurements, the skin contact surface is required to displace smoothly in response to contact or pressure by the skin of the subject thereon. Furthermore, the design of the skin contact surface should allow functional engagement with the skin of the subject. Thus, the skin contact member is integrally formed with a first end of a flexible member allowing the smooth displacement thereof. A housing of the device is integral with a second end of the flexible member such that the skin contact member displaces along at least one axis with respect to the static housing. The integration of the three elements, the skin contact member, the flexible member, and the housing forms a continuous structure, which is advantageous and allows to obtain the desired accuracy of the fine measurements. The integration of the three parts is typically performed by one or more over-molding processes.

Disclosed herein are methods, systems, and media for pressure sensing for physiological measurements. In some embodiments, a method comprises: obtaining sensor data from one or more sensors disposed in or on a wrist-worn device worn on a wrist of a user. The method may involve determining, based on the sensor data, a measure of a contact pressure of a bottom portion of the wrist-worn device on the wrist of the user. The method may involve based on the measure of the contact pressure, providing one or more instructions to the user to adjust the wrist-worn device to bring about a change in the contact pressure toward a target contact pressure or a target contact pressure range. The method may involve initiating a physiological measurement of the user using other sensors disposed in or on the wrist-worn device.

A system and method for monitoring activities of a user. Sensor measurements are performed utilizing a sensor array of sensor tags. User activities are detected utilizing the sensor array of the sensor tags. The user activities are communicated to a hub associated with the sensor array of sensor tags.

An infant sleep device may include a platform for supporting an infant, a base upon which the platform is supported, and one or more weight sensors positioned to measure weight of an infant positioned on the platform.

A monitoring device for monitoring of vital signs of a living organism comprises at least two electrode pins for receiving an electrical activity of the living organism and an optical sensor for sensing a pulse of the living organism, wherein the monitoring device has a compact form and the at least two electrode pins and the optical sensor are integrated in the monitoring device.

A head-mounted device capable of more highly accurately measuring the physical conditions of a wearer as a worker that are necessary for estimating the possibility of heat stroke is provided. A head-mounted device includes an outer shell; a first channel as a gap between a head of a wearer and the outer shell; a second channel provided in the outer shell and connected to the first channel; a fan configured to send air from one of the first channel and the second channel to the other; a salinity sensor configured to measure salt concentration of sweat of the wearer; a first humidity sensor configured to measure an absolute humidity of intake air entering one of the first channel and the second channel; and a second humidity sensor configured to measure an absolute humidity of exhaust air exiting from the other of the first channel and the second channel.

An exemplary embodiment of the present disclosure provides a system for assessing joint health comprising a joint sensor configured to measure at least one non-acoustic characteristic of a joint during movement; a bioimpedance sensor configured to measure bioimpedance of a joint structure exposed to electrical current at a plurality of frequencies; a processor; and a memory, the memory comprising instructions that, when executed by the processor, cause the processor to provide an assessment of joint health through interpretation of measurements from the joint sensor and the bioimpedance sensor.

An apparatus for minimally-invasive, including non-invasive, prevention and/or treatment of hydrocephalus and method for use of the same are disclosed. In one embodiment of the apparatus, a housing is sized for superjacent contact with a skull having a fontanel. Within the housing, a compartment includes a pressure applicator, such as a fluid-filled bladder, under the control of a pressure regulator. The pressure applicator is configured to selectively apply an external pressure to the fontanel. The compartment includes a pressure sensor configured to measure intracranial pulse pressure of the fontanel. Further, in one embodiment, the apparatus can cause pulse pressure modulation by adjusting the intracranial pulse pressure via the pressure applicator. This enables a non-invasive measurement of the pulse pressure and modulation thereof in infants, for example.

A multi-functional health monitoring mat which enables the measurement of—but not limited to the following parameters: Weight, Plantar pressure, Bio-impedance for body composition, and Cardiovascular based measurements, such as: Electrocardiogram (ECG), Ballistocardiogram (BCG) from which additional health indicating analytics can be further extracted. The mat will be comprised of 3 separate layers: (1) A Bottom Layer, used for weight measurement, comprising force measurement sensors (2) A Middle Layer, used for pressure measurement, comprising pressure sensors in a matrix, and (3) A Top Layer, used for bio-impedance measurement, comprising conductive sensors, distributed throughout the top layer, enabling random orientation of the feet. In addition, there will be an electronic sub-system to enable communication of data and information from the bath mat to a mobile application. Measurements taken from the mat are transmitted to a software application on a mobile phone and data is used to provide feedback to the user.

Example embodiments include devices and systems that detect apnea events of a user. The device includes a first sensor configured beside the head of the user for capturing snoring sounds of the user, a second sensor configured on one finger of the user for capturing cardiovascular parameters of the user, a third sensor configured under the trunk of the user for capturing e breathing movements of the user, a data recorder that is connected with the first sensor, the second sensor and the third sensor for receiving recordings therefrom, and a clock for synchronizing the recordings in real time. The recordings include one or more breathing events including snoring events, heart rate and SPO.sub.2 conjunction spikes, and breathing movement cessations. The time periods that apnea events are impossible can be excluded according to a combination of the breathing events, and the apnea events can be detected thereafter.
