Abstract
A smart patch includes a computing device to monitor user health metrics. The smart patch also includes an adhesive coupled to a cradle with an opening and coupled to at least two electrodes capable of electrically coupling to the user. The computing device contains one or more sensors, a battery and a sensor window. The sensors are configured to interface with the user to generate physiological data associated with the user's health. The battery is configured to power the sensors. The computing device is removably coupled to the cradle. The cradle is configured to engage the computing device securing the computing device to the adhesive. The electrodes electrically couple to the user's skin and conduct electrical signals between the user and the computing device.
Core Innovation
The invention relates to a smart patch to monitor health metrics of a user. The smart patch includes an adhesive for attaching the smart patch to skin and at least two electrodes attached to the adhesive that are capable of electrically coupling to the user. A cradle is removably coupled to the adhesive, where the cradle includes a cradle opening for access to the skin and at least two electrode openings.
The invention further includes a computing device that is selectively removable from the cradle. The computing device includes a housing with a top housing portion and a bottom housing portion, a main printed circuit board (PCB), a sensor window in the bottom housing portion, and a battery. Circuitry coupled to the at least two electrodes measures electrical activity from the skin of the user, and one or more sensors interface with the skin through the sensor window and the cradle opening to generate physiological data associated with health metrics.
To provide electrical connectivity and compact modular construction, the computing device includes a sensor PCB including PCB contacts configured to electrically connect to the one or more sensors. A flexible PCB connector electrically connects the main PCB to the sensor PCB. The computing device includes at least two metal connecting pads such that, when the computing device is coupled to the cradle, the electrodes protruding from the cradle surface are electrically connected to the PCB contacts via the metal connecting pads. A mechanical holder secures the battery sandwiched between the sensor PCB and the main PCB, while also securing the main PCB to the bottom housing portion.
Claims Coverage
The document includes one independent claim (clm-00001). It defines a removable smart patch architecture combining an adhesive electrode interface with a cradle and a selectively removable computing device containing windows, battery, PCBs, and electrical/mechanical coupling through metal connecting pads.
Adhesive electrode interface with removably coupled cradle and protruding electrodes
A smart patch includes an adhesive attached to skin with at least two electrodes electrically coupling to the user, and a cradle removably coupled to the adhesive that provides a cradle opening and electrode openings so the electrodes protrude through the electrode openings when the cradle is coupled.
Selectively removable computing device with housing, sensor window, battery, and electrical measurement circuitry
A computing device that is selectively removable from the cradle includes a housing with a sensor window, a battery, circuitry coupled to the at least two electrodes to measure electrical activity from skin, and one or more sensors configured to interface with skin through the sensor window and cradle opening to generate physiological data associated with health metrics.
Stacked sensor PCB and flexible connector with electrode electrical connection via metal connecting pads
The computing device includes a sensor PCB with PCB contacts connected to the one or more sensors, a flexible PCB connector electrically connecting the main PCB to the sensor PCB, and at least two metal connecting pads that electrically connect the electrodes protruding from the cradle surface to the PCB contacts when the computing device is coupled to the cradle.
Battery sandwiched by mechanical holder securing main PCB to housing
A mechanical holder secures the battery sandwiched between the sensor PCB and the main PCB, and further secures the main PCB to the bottom housing portion.
Across the single independent claim, the core inventive coverage is the combination of an adhesive-mounted electrode interface with a removably coupled cradle that positions protruding electrodes, and a selectively removable computing device that uses a sensor window and cradle opening for sensor access, includes stacked sensor electronics with a flexible connector, connects electrode terminals through metal connecting pads, and mechanically sandwiches the battery while securing the main PCB.
