Samsung patents watch design that measures body composition via side electrodes
Samsung has been granted a patent for a wearable device, likely a smartwatch, that integrates biometric sensors into its side casing. The design uses a flexible circuit board to connect electrodes on the side of the watch to a sensor module, allowing it to measure body composition when the user's skin touches the device.
In the filing’s own words
An example wearable device includes a housing including a first surface facing a first direction, a second surface facing a second direction opposite to the first direction, and a third surface at least partially enclosing a space between the first surface and the second surface; a printed circuit board disposed between the first surface and the second surface; a speaker disposed in a space defined by the third surface between the first surface and the second surface; a flexible printed circuit board that is disposed to surround at least a portion of the speaker device, connects the speaker device and the printed circuit board, and contains a conductive connector in a first area facing the third surface; and at least one first electrode that is connected to the conductive connector to be connected to the flexible printed circuit board. The third surface includes at least one opening formed in a second area corresponding to the position of the speaker device and a second opening formed in a third area spaced apart from the second area, and at least a portion of the at least one first electrode is exposed to the outside of the third surface of the housing through the second opening.
What exactly they claim (claim 1)
1. A wearable device comprising: a housing comprising a first surface facing a first direction, a second surface facing a second direction opposite to the first direction, and a third surface at least partially surrounding a space between the first surface and the second surface; a printed circuit board disposed between the first surface and second surface of the housing; a speaker device disposed in a cavity formed by the third surface of the housing, between the first surface and second surface of the housing; a flexible printed circuit board disposed to surround at least a part of the speaker device and electrically connecting the speaker device and the printed circuit board, and comprising a conductive connector in a first area facing the third surface of the housing; and at least one first electrode connected to the conductive connector and electrically connected to the flexible printed circuit board, wherein the third surface of the housing comprises: at least one first opening formed in a second area corresponding to a position of the speaker device; and a second opening formed in a third area spaced a specified distance apart from the second area, wherein the at least one first electrode is at least partially exposed to the outside of the third surface of the housing through the second opening and is configured to be in contact with at least a portion of a user's body, wherein the wearable device further comprises: a plurality of second electrodes exposed to the outside through the second surface of the housing; and a biometric sensor module electrically connected to the at least one first electrode and the plurality of second electrodes, and wherein the biometric sensor module provides an electrical signal or data value corresponding to body composition information of a user, based on contact of the user's body with at least one of the at least one first electrode or the plurality of second electrodes.
