Patents by Inventor Ahyeon KOH

Ahyeon KOH has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20210393204
    Abstract: Skin-mounted or epidermal devices and methods for monitoring biofluids are disclosed. The devices comprise a functional substrate that is mechanically and/or thermally matched to skin to provide durable adhesion for long-term wear. The functional substrates allow for the microfluidic transport of biofluids from the skin to one or more sensors that measure and/or detect biological parameters, such as rate of biofluid production, biofluid volume, and biomarker concentration. Sensors within the devices may be mechanical, electrical or chemical, with colorimetric indicators being observable by the naked eye or with a portable electronic device (e.g., a smartphone). By monitoring changes in an individual's health state over time, the disclosed devices may provide early indications of abnormal conditions.

  • Patent number: 10820862
    Abstract: Provided are devices and methods capable of interfacing with biological tissues, such as organs like the heart, in real-time and using techniques which provide the ability to monitor and control complex physical, chemical, biochemical and thermal properties of the tissues as a function of time. The described devices and methods utilize micro scale sensors and actuators to spatially monitor and control a variety of physical, chemical and biological tissue parameters, such as temperature, pH, spatial position, force, pressure, electrophysiology and to spatially provide a variety of stimuli, such as heat, light, voltage and current.
