Abstract:
The present invention relates to portable devices for point-of-care diagnostics that can perform measurements on a sample (e.g., blood, serum, saliva, or urine) and relay data to an external device for, e.g., data analysis. The device can comprise a paper-based diagnostic substrate and a base substrate that include electronic circuitry and electronic elements necessary for performing the measurements. The device can also comprise an antenna for near field communication with an external device. Another aspect of the invention relates to methods of using these devices.
Abstract:
A device includes a wirelessly enabled energy harvesting device, an energy storage component, a DC-DC converter, and a functional circuit. The energy storage component is electrically coupled to the wirelessly enabled energy harvesting device for storing energy harvested by the wirelessly enabled energy harvesting device from a wireless transmitting device positioned adjacent to the device. The DC-DC converter is electrically coupled to the energy storage component for receiving a voltage output from the energy storage component and converting the received voltage output to a second voltage level to provide power to one or more components of the device. The functional circuit is for measuring a concentration of a substance in a fluid sample. The functional circuit is coupled to the DC-DC converter such that the functional circuit obtains at least a portion of the power provided by the DC-DC converter.
Abstract:
System, devices and methods are presented that integrate stretchable or flexible circuitry, including arrays of active devices for enhanced sensing, diagnostic, and therapeutic capabilities. The invention enables conformal sensing contact with tissues of interest, such as the inner wall of a lumen, a nerve bundle, or the surface of the heart. Such direct, conformal contact increases accuracy of measurement and delivery of therapy.

The invention enables conformal sensing contact with tissues of interest, such as the inner wall of a lumen, a the brain, or the surface of the heart. Such direct, conformal contact increases accuracy of measurement and delivery of therapy. Further, the invention enables the incorporation of both sensing and therapeutic devices on the same substrate allowing for faster treatment of diseased tissue and fewer devices to perform the same procedure.
Abstract:
The present invention describes multilayered adhesive structures that can be used as adhesives to mount wearable devices onto the skin. The multilayered adhesive structures can comprise a buffer layer sandwiched between two adhesive layers, a first adhesive layer adhering the multilayered adhesive structure to the wearable device and a second adhesive layer adhering the buffer layer to the skin. The buffer layer separates or isolates the wearable device from the skin. By mechanically buffering the wearable device from the skin, the multilayered adhesive structures permit the devices to be skin-mounted for an extended period of time (e.g., a few hours or days) without causing moisture-associated skin injuries such as erythema, maceration, and irritation or inflammation.
