To provide an electrocardiographic measurement apparatus that can prevent a variety of subjects from having discomfort when the apparatus is attached to the subjects. The electrocardiographic measurement apparatus includes: a plurality of electrodes that has a length along a circumferential direction of an upper arm, the length being variable in accordance with a length in the circumferential direction of the upper arm, and detects an electric potential from the upper arm that is brought into contact with the electrodes; and a device body that generates electrocardiographic information based on the electric potential detected by the plurality of electrodes.

Provided are a method, server, and computer program for designing a customized headgear for transcranial direct current stimulation. According to one embodiment, there is provided a method for designing a customized headgear for transcranial direct current stimulation performed by a computing device and applying electrical stimulation to a preset target point in a brain of a subject, the method including: acquiring a head image of the subject; generating a headgear mask by using the acquired head image; generating a stimulator mask by using an optimal stimulation position combination for applying the electrical stimulation to the preset target point; and generating a customized headgear mask for the subject by performing a subtraction operation between the generated headgear mask and the generated stimulator mask.

A device and system for promoting more recuperative sleep by regulating a user's body temperature. This may be done by using a series of devices that measure information about the user both while they are awake and while they are asleep, communicate that information to a processing unit, and create an ideal body temperature range profile based on that information. A temperature stimulus device may ensure that the core body temperature of the user stays substantially within the ideal body temperature range. By keeping the core body temperature of the user within the calculated range, the device and system will ensure deeper, and therefore more recuperative, sleep.

An electronic device and a wearable electronic device are provided in implementations of the disclosure. The electronic device includes a housing frame, a button assembly, and a circuit assembly. The housing frame has an inner cavity and a first through hole. The first through hole communicates with the inner cavity and an external space outside the housing frame. The button assembly includes a first conductive member and a second conductive member. The first conductive member is connected to the housing frame and at least partially in the external space. The second conductive member is at least partially in the first through hole. The first conductive member elastically abuts against the second conductive member, so that the first conductive member is in electrical communication with the second conductive member. The circuit assembly is disposed in the inner cavity.

The present disclosure is directed to a solid body for a biomedical device, wearable by a patient and configured to acquire one or more physiological parameters of the patient. The solid body includes a first rigid portion, a second rigid portion and a connection portion of flexible type which couples the first and the second rigid portions to each other; and a control circuitry accommodated inside the first and/or the second rigid portions. The connection portion is interposed between the first and the second rigid portions, is integral therewith and is deformable so as to allow a relative movement of the first and the second rigid portions. The first and the second rigid portions are physically couplable to a first and to a second ECG electrode to couple the solid body to the torso of the patient. When the rigid portions are coupled to the ECG electrodes, the control circuitry is electrically coupled to the ECG electrodes and is configured to acquire, through the ECG electrodes, respective electrical signals indicative of said one or more physiological parameters.

An electrode-equipped band includes a first band section and a second band section extending along a longitudinal direction. The second band section includes a first stretchable section, an electrode, a second stretchable section, a ring member, a fold-back section, and a joining section. The first stretchable section has first stretchability along the longitudinal direction. The electrode is provided on a first surface of the first stretchable section. The second stretchable section overlaps with the first stretchable section on a side of a second surface of the first stretchable section, and has second stretchability that allows greater stretch along the longitudinal direction than the first stretchable section. The ring member is provided at a position corresponding to a band end along the longitudinal direction of the second band section, and may be connected to the first band section.
