Abstract
A smartwatch includes a multiresolution touch interface, a second electrode, and a third electrode. The transparent conductive screen includes a first electrode, a display layer, and an array of IR sensors. The display layer of the transparent conductive screen includes a plurality of display pixels, and is positioned beneath a bottom surface of the transparent conductive screen. The array of IR sensors of the transparent conductive screen is configured to detect infrared light transmitted through the transparent conductive screen. The second electrode is communicatively coupled to the first electrode. The first electrode and the second electrode together are configured to measure a bioimpedance of a user of the smartwatch. The third electrode is coupled to a bottom portion of the smartwatch, and is configured to contact an extremity of the user. The first electrode and the third electrode together are configured to measure ECG data associated with the user.
Core Innovation
The invention provides a smartwatch that integrates a multiresolution touch interface with user bioimpedance and ECG sensing. A transparent conductive screen is used as a first electrode, and an electrode contact is positioned above the display layer and coupled to the first electrode. A display layer having a plurality of display pixels is positioned beneath a bottom surface of the transparent conductive screen.
The smartwatch further includes a second electrode communicatively coupled to the first electrode, where the first electrode and the second electrode together are configured to measure bioimpedance of a user. The smartwatch also includes a third electrode coupled to a bottom portion of the smartwatch and configured to contact an extremity of the user. The first electrode and the third electrode together are configured to measure ECG data associated with the user.
An array of IR sensors detects infrared light transmitted through the transparent conductive screen. The electrode contact is positioned between at least a portion of the transparent conductive screen and at least a portion of a transparent adhesive to facilitate conductivity from the first electrode to a printed circuit board. A transistor layer between the display layer and the array of IR sensors operates the plurality of display pixels, and an insulating opaque substrate is positioned between the transistor layer and a PCB of the multiresolution touch interface.
Claims Coverage
The provided material includes two independent claims. The independent claims center on a transparent conductive screen, IR sensing transmitted through the screen, and electrode/contact structures for sensing bioimpedance and ECG data, together with transistor-layer and insulating-substrate relationships in the multiresolution touch interface claim.
