The present disclosure is directed to systems and methods of collecting environmental and/or biometric information and/or data using a chronic monitoring apparatus that includes a wearable expandable support structure to wirelessly receive power via a wireless power transfer antenna disposed in, on, or about the wearable expandable support structure. The chronic monitoring apparatus includes power receiver circuitry, data transmission circuitry, sensor circuitry, and control circuitry. The wearable expandable support structure maintains close contact between at least a portion of the sensor circuitry and the wearer of the chronic monitoring apparatus without requiring the use of adhesives or other bonding agents. The chronic monitoring apparatus communicates the collected environmental and/or biometric information to external data collection circuitry. The components included in the chronic monitoring apparatus are sealed within the wearable expandable support structure providing a rugged, reliable, resilient and waterproof system that is biocompatible, non-irritating and does not require the use of adhesives.

The present invention provides a device for non-invasive monitoring and/or detection of diabetes in a subject based on detection of volatile organic compounds (VOCs) in the exhaled breath of a subject. The device comprises a functionalized carbon nanotube-based array sensor which can reversibly bind VOCs, which alters the electrical conductivity of the sensor array, which can be interpreted to monitor and/or diagnose diabetes.

A medical device may include a lower housing, a printed circuit board (PCB) received within the lower housing, a top housing, two plungers received in gaps within the top housing, and strain gauges mounted to the PCB. The strain gauges may define two polygons aligned with the two plungers. The two plungers may be in contact with the strain gauges such that a force on a plunger is transferred to the strain gauges in contact with the respective plunger. The load magnitude and load location may be determined based on the measured strain of the strain gauges.

Disclosed is an electronic skin sensor patch which is attached to a skin of a user and measures a bio signal, the electronic skin sensor patch including: a patch body including a frame which is formed with an opening and is made of a mechanical metamaterial; a sensing unit disposed on a first region of the patch body; a sensor system unit disposed on a second region of the patch body and configured to maintain a nonadherent state with the skin; and a wiring disposed along the frame of the patch body and configured to connect the sensing unit and the sensor system unit.

A myoelectric sensor for detecting myoelectric signals which accompany body movement includes: a wearing band that is elastic, expandable, and circular, and that is worn around a limb to surround the limb tightly; myoelectric detection units a plurality of which are disposed in the circumferential direction on the wearing band with intervals therebetween so as to cause each of a plurality of myoelectric detection electrodes to be in close contact with the surface of the limb, and which detect myoelectric signals from corresponding positions on the limb using the myoelectric detection electrodes; and connection cables that electrically connect mutually adjacent myoelectric detection units and thereby transmit the myoelectric signals. The connection cables each include a bent portion, the bent shape of which changes in response to changes in the distance between the mutually adjacent myoelectric detection units.

A load cell apparatus for use with a bed includes a housing having a top portion and a bottom portion, and a load cell device held by the bottom portion of the housing. The load cell device is structured to generate a signal having a magnitude that is proportional to a first force being applied to the load cell device. The load cell apparatus also includes a button member held by the housing in a manner wherein the button member is structured to engage the load cell device and apply the first force to the load cell device in response to a second force being applied to the top portion of the housing. Also, various systems for monitoring parameters such as weight, sleep quality, fall risk, and/or pressure sore risk that may incorporate such a load cell apparatus.

An intravascular sensor device can be used to guide treatment of a diseased blood vessel in the body of a patient. In some examples, the intravascular sensor device includes a pressure sensor and an ultrasound transducer. The intravascular sensor device is used to measure a pressure within the diseased blood vessel and acquire an ultrasound image of the diseased blood vessel. The pressure may be measured during hyperemic blood flow that is caused by a pharmacologic vasodilator drug. The measured pressure can be used to calculate a fractional flow reserve value. The ultrasound image can be used to determine a physical dimension of the blood vessel, such as cross-sectional area. The fractional flow reserve value and physical dimensions of the blood vessel can be used to optimize patient treatment.

A jig includes a base and one or more movable blocks. The base has an upper surface, which is configured to receive a substrate shaped as a flattened polyhedron having multiple facets. The one or more movable blocks are configured to move on the base so as to fold respective ones of the multiple facets, and to hold the substrate in a folded three-dimensional configuration.

Provided is a biological electrode and a biological electrode-equipped wearing tool, in which a contact surface having a certain surface area is suitably brought into intimate contact with a living body, and a suitable electrical distribution is obtained. The biological electrode includes: a thin-plate-like or sheet-like wiring substrate having a lead wire portion to be connected with equipment; a plurality of electrode convex portions disposed on a surface of the wiring substrate in a state of being electrically connected with the lead wire portion; and a conductive cloth portion which is superimposed on the wiring substrate through the electrode convex portions. The conductive cloth portion is to be contacted with the surface of a living body, and electrically connected to the living body.
