A patch-type biomedical device cover that includes a cover film, a first adhesive member, and a second adhesive member. The cover film includes an upper cover film and a lower cover film and is configured to be folded into a bag when in use so as to be able to accommodate a temperature sensor therein. The first adhesive member is on an outside surface of the lower cover film. The second adhesive member is on an inside surface of the lower cover film. The second adhesive member is configured to adhere the temperature sensor to the lower cover film and to adhere an edge portion of the upper cover film to an edge portion of the lower cover film so as to close the upper cover film and the lower cover film to form the bag.

A body electrode unit includes a body electrode configured to be attached to a body, and a release sheet to which the body electrode is attached. The body electrode includes at least a first electrode and a second electrode. The first electrode and the second electrode are put together to form a single continuous shape. The release sheet includes a first processed part configured to facilitate at least one of a separation and a bending of the release sheet, the first processed part being provided in a first area between a position at which the first electrode is attached and a position at which the second electrode is attached.

A body electrode unit includes a body electrode and a release sheet to which the body electrode is attached. The body electrode includes a first electrode configured to stimulate a muscle of a body, a second electrode, and a third electrode. The second electrode and the third electrode are configured to detect a physiological signal from the muscle that is stimulated by the first electrode. The body electrode also includes a first connection portion arranged between the first electrode and the second electrode, and a second connection portion arranged between the third electrode and one of the first electrode and the second electrode. The first connection portion has at least one first direction changing part configured to change a direction in which the first connection portion extends, such that at least one of a distance and an angle between the first electrode and the second electrode is adjustable.

A system can include one or more electrodes; a sensor structure configured to position electrodes over a surface of a body that includes an artery. A capacitance sensing circuit can be coupled to the electrodes and configured to acquire capacitance values of the electrodes over a predetermined time period. The capacitance values can correspond to a distance between the body surface and the at least one electrode. Processor circuits can be configured to generate APW data from the capacitance values. Corresponding methods and devices are also disclosed.

Disclosed examples include those directed to detecting and remediating detachment of electrodes from a patient. In an example, a system calculates a Pearson correlation coefficient between: (1) power spectral density of the noise and (2) power spectral density of a recorded signal (e.g., from an electrode being operated in free-run EMG mode). If the recorded signal correlates with the noise, then the system notifies the user of presence of noise (e.g., the fallen electrode). Otherwise, the recorded signal is considered as the signal of interest (e.g., a valid EMG signal).
