Prior art establishing that the general ‘multi-sensor wearable + body-area network + cloud analytics’ system architecture and its building blocks were collected and published by 2010 — useful against later claims to the bare system architecture. General anchor.

VitalConnect VitalPatch (2016) — adhesive chest patch with single-lead ECG and multi-parameter monitoring (2016)

  • id: vitalconnect-vitalpatch-2016
  • corpus: private
  • form factor: patch
  • creator: VitalConnect, Inc.
  • disclosure: VitalConnect, Inc. ‘VitalPatch’ biosensor, FDA-cleared as a single-use adhesive chest patch with single-lead ECG, heart rate, heart-rate variability, respiratory rate, skin temperature, posture, activity, and fall detection, streamed wirelessly to a smartphone/relay; 7-day wear (later 14-day variants).
  • ip status: patented
  • sensors: sensor-ecg, sensor-accelerometer, sensor-skin-temperature
  • algorithms: algo-hr, algo-hrv, algo-respiratory-rate, algo-activity-classification, algo-posture-detection, algo-fall-detection, algo-arrhythmia-classification
  • prior art notes: Discloses a single-use adhesive chest patch deriving single-lead ECG, HR, HRV, respiratory rate, skin temperature, posture, activity, and falls in one body-worn unit, streamed wirelessly — i.e. a packed multi-parameter vital-signs patch. Anticipates multi-parameter ECG-patch claims combining any subset of those measurements in one adhesive form factor from 2016. Product-side anchor for the patch × multi-parameter-vitals cross-cut alongside [[fda-k113862-irhythm-zio-patch-2011]] (the AFib-focused variant).

Gao et al. (Javey group) (2016) — fully integrated wearable sensor array for multiplexed in-situ perspiration analysis (2016-01-28)

Any wearable claim reciting ‘a band-form device with an array of two or more electrochemical sweat-analyte sensors plus a temperature sensor for compensation, with integrated electronics and wireless output’ reads on Gao/Javey 2016. Anchor for the sweat-electrochemical-sensing cross-cuts on the real side; [[bandodkar-wang-2014-wearable-electrochemical-sensors-review]] is the contemporaneous review.

Prior art establishing that the modality/form-factor combinations enumerated here were collected and surveyed by 2018; useful against later claims to those combinations. General anchor.
