Abstract: A transdermal oxygen patch measures an oxygen concentration based on transcutaneous oxygen diffusing through an epidermal surface of a patient. Transcutaneous oxygen differs from hemoglobin-bound oxygen often measured in a patient blood flow. The patch employs an indicator responsive to an oxygen presence for emitting light having an intensity and lifetime (duration) based on the oxygen presence. An optical receptor is in communication with logic for receiving the intensity of emitted light and computing the oxygen concentration based on the received intensity and lifetime (duration). A wireless transmitter conveys the results to a base station or monitoring counterpart for untethered patient monitoring. Low power demands and circuit footprint are amenable to a wearable device such as a patch for continuous use.

Abstract: Increased regulation reflects individuals' growing concerns about sharing their health data. But, if left unaddressed, these regulations act as a barrier to healthcare researchers and providers accessing the real-world health data they need for AI-powered health advances. Accordingly, the inventors have established a decentralized ledger based self-sovereign data management platform for individuals. Via the platform an individual is provided a personalized health wallet to supporting self-sovereign data management giving them control and custody of their own health data. The platform provides for data credentialing to ensure quality and support of verifiable claims, e.g., about an individuals' consent to share and/or a third party research project having ethics approval, zero-knowledge proofs to protect individual privacy and promote secure data sharing, and support for privacy-preserving audit, accountability and compliance relating individuals' consent and data sharing.
