A recently filed patent (Publication Number: US20230248288A1) describes an electronic device designed for monitoring physiological signals in mammals. The device consists of a rigid housing with flexible wings that conform to the surface of the mammal. The wings contain embedded electrodes and electrode traces that provide conformal contact with the mammal's surface and transmit electrical signals to a printed circuit board assembly housed within the rigid housing. The device also includes hinge portions that allow the wings to flex freely.

The patent claims also describe additional features of the electronic device. Each wing may have an adhesive and the electrodes may be in the same plane as the adhesive. The wings may also have thinner rims to prevent their release from the mammal's surface. The rigid housing may have dimples to allow for airflow between the housing and the mammal's surface. The device may also include a measuring instrument, such as an accelerometer, to detect motion signals in one or three axes. The motion signals are collected in time with the physiological signals, and a motion artifact is identified when the two signals match. The device may also have an event trigger, supported by the rigid housing, and gaskets for sealable attachment.

The patent also describes a method for monitoring physiological signals using the electronic device. The method involves attaching the device to a mammal, detecting physiological signals using the electrodes, and detecting secondary signals using a measuring instrument. The physiological signals are then compared to the secondary signals to identify any artifacts. The identification of artifacts may involve comparing the frequency spectrum of the physiological signals to the frequency spectrum of the secondary signals. The secondary signals can include motion signals, which can be used to derive the activity and position of the mammal.

Overall, this patent describes an electronic device and method for monitoring physiological signals in mammals, with features designed to ensure conformal contact, minimize signal distortion during movement, and identify motion artifacts. The device has potential applications in various fields, including healthcare and sports performance monitoring.
