A bioelectrode in which an electrode layer can deform in association with the unevenness of the installation surface of the biological surface so as to adhere to the installation surface, and which can be easily transported and stored, a production method and an installation method for the bioelectrode. It is a bioelectrode in which a flexible electrode that is to directly contact a biological surface is formed from an electrode layer that includes a conductive polymer and deforms in association with an installation surface of the biological surface so as to adhere to the installation surface, and an elastomer layer that is layered on one surface side of the electrode layer and deforms in association with the installation surface and the electrode layer, wherein the flexible electrode is bonded to a water-permeable layer that serves as a support via a water-soluble sacrificial layer that includes a water-soluble material.

A wearable patch for sports can include a patch substrate configured to support a plurality of components, and to allow the patch to be attached to a skin of a user engaged in a sporting activity. The patch can further include a sensor implemented at least partially within the patch substrate and configured to sense a condition of the user. The patch can further include a transmitter circuit in communication with the sensor and configured to transmit information representative of the sensed condition to a location external to the wearable patch.

Devices, methods and systems related to wearable patch having blood alcohol content detector. In some embodiments, a wearable patch can include a patch structure having one or more layers and configured to allow the patch to be worn by a user, and an analyzer component implemented on or at least partially within the patch structure and configured to measure alcohol content level in the user. The wearable patch can further include an interface component implemented on or at least partially within the patch structure and in communication with the analyzer component, with the interface component being configured to provide a notification based on the measured alcohol content. In some embodiments, such a wearable patch can be a part of a system such as a monitoring system or a compliance system.

Devices, systems, and methods are provided herein for delivering medication (e.g., insulin) via a wearable pump having a patch-style form factor for adhesion to a user's body. The reusable pump may be coupled to a disposable cap housing a microdosing system for delivering precise, repeatable doses of medication to a cannula configured to deliver medication to a target infusion area beneath the user's outer skin layer. The system further may include an applicator for inserting the cannula into the user's skin and/or applying an adhesive pad to the skin.

Systems and methods for a microfluidic biosensor patch and health monitoring system may include an iontophoresis module, a multi-inlet microfluidic sweat collection and sampling module, and a molecularly imprinted polymer (MIP) organic compound sensor module. An iontophoresis module may provide for stimulation of a biofluid sample. A biofluid may be a sweat sample. Stimulation may be achieved via electrostimulation and/or application of hydrogel. A microfluidic sweat collection and sample module may include several adhesive layers with carefully designed inlets, channels, a reservoir, and an outlet for the efficiently collection and sampling of biofluid. A MIP sensor module may quickly and accurately identify concentrations of key metabolites present in a biofluid sample which may indicate certain health conditions.

A patch and sensor assembly has a biosensor housed in a reusable portion that connects to a mapping and localization system (MLS) via biosensor wires. A disposable portion has an electrode layer through which signals are transmitted to the MLS via ACL wires. The biosensor and ACL wires extend through a single cable exiting the reusable portion. The disposable portion includes an adhesive layer for adhering the electrode layer to a patient, on the electrode layer, and an engagement element for detachably receiving at least a portion of the housing of the reusable portion. The reusable portion includes a housing in which the biosensor has biosensor wires that exit the reusable portion. The housing is also adapted to carry and/or provide support to an ACL contact member responsive to the electrode layer of the disposable portion, and ACL wires that exit the reusable portion.

Examples described herein include sensor devices for measuring a parameter of a user. The sensor devices may include a reusable portion (e.g., a sensor). The sensor devices may include one or more weakened portions that may fracture on removal of a portion of the sensor device from the user. Fracturing the weakened portions may expose the reusable portion (e.g., the sensor). Accordingly, the reusable portion may be more readily observed and collected for reuse.

A system for monitoring fetal wellbeing over time during pregnancy includes a sensor coupled to a pregnant woman; a processor communicatively coupled to the sensor; and a computer-readable medium having non-transitory, processor-executable instructions stored thereon. Execution of the instructions causes the processor to perform a method including: acquiring a signal from a sensor; processing the signal to identify and extract a parameter of interest from the signal; and analyzing the parameter of interest to determine a degree of fetal wellbeing. The parameter of interest may include one or more of: an average fetal heart rate, an average fetal heart rate variability, a fetal kick or movement count, an average placental oxygenation level, an average placental temperature, an average placental pH, an average amount of amniotic fluid, a fetal heart rate profile, a fetal heart rate variability profile, and a fetal movement profile.

Provided is a waterproof device that is impervious to water and can also use an air cell as a power source. The waterproof device of the present disclosure is worn on the body and includes a circuit unit, a power source, and an exterior package that protects the circuit unit and the power source. At least a part of the exterior package is composed of a water-repellent air-permeable sheet. The water-repellent air-permeable sheet has a water pressure resistance of 12 kPa or more.

A patchable biosensor includes a substrate extending in a longitudinal direction and being stretchable for being patched to a surface of a living body and an electronic component disposed on a one-side surface in a thickness direction of the substrate and extending in the longitudinal direction. The longitudinal direction of the electronic component crosses the longitudinal direction of the substrate.
