- disclosure: Pantelopoulos A, Bourbakis NG. ‘A survey on wearable sensor-based systems for health monitoring and prognosis.’ IEEE Transactions on Systems, Man, and Cybernetics, Part C (Applications and Reviews) 2010;40(1):1-12.
- ip status: public-domain
- sensors: sensor-ecg, sensor-ppg, sensor-spo2, sensor-accelerometer, sensor-skin-temperature, sensor-respiration-impedance
- algorithms: algo-hr, algo-arrhythmia-classification, algo-spo2-estimation, algo-fall-detection, algo-activity-classification
- prior art notes: Surveys, as of 2010, the architecture and components of wearable health-monitoring systems — sensors (ECG, PPG, SpO2, accelerometry, temperature, respiration), garment- and patch- and watch-based form factors, on-body processing, wireless body-area networking, and the analytics (arrhythmia, fall, activity, deterioration prediction). 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.

Polar H10 (2017) — research-grade chest-strap ECG heart-rate sensor (2017-01)
- id:
polar-h10-chest-strap-2017 - corpus: private
- form factor: garment
- creator: Polar Electro Oy
- disclosure: Polar Electro Oy. ‘Polar H10’ chest heart-rate sensor, released 2017 — a chest strap with two dry electrodes deriving a single-lead ECG, computing R-R intervals and heart rate, with onboard 1-session memory, dual-broadcast (BLE + ANT+ + 5 kHz GymLink), an accelerometer (relative orientation), and well-documented R-R-interval accuracy (often used as a gold-standard reference for consumer wearables).
- ip status: patented
- sensors: sensor-ecg, sensor-accelerometer
- algorithms: algo-hr, algo-hrv, algo-arrhythmia-classification
- prior art notes: Discloses a chest strap with two dry electrodes deriving single-lead ECG, with on-strap R-R-interval computation, multi-protocol broadcast (BLE + ANT+ + the 5 kHz GymLink legacy band), and accelerometer-assisted noise rejection. Anticipates chest-strap-ECG claims combining ‘dry textile/elastic chest electrodes’, ‘on-strap derivation of R-R intervals and HR’, and ‘multi-protocol simultaneous wireless broadcast’ from 2017. Product-side anchor for the garment/patch × ECG strap cross-cut; refines [[polar-sport-tester-pe2000-1982]].
Withings ScanWatch (2020) — hybrid analog watch with PPG, SpO2 pulse oximetry, single-lead ECG, and accelerometer (2020-01-05)
- id:
withings-scanwatch-2020 - corpus: private
- form factor: watch
- creator: Withings SA
- disclosure: Withings (Nokia/Withings). ‘ScanWatch’, announced January 2020 (CE-marked 2020; FDA cleared 2022) — a hybrid analog wristwatch integrating a reflectance-PPG sensor (heart rate, irregular-rhythm screening), an SpO2 (pulse-oximetry) measurement, a single-lead ECG (back electrode plus a bezel electrode touched by the opposite hand, with AF detection), a 3-axis accelerometer, and an altimeter — with sleep and activity tracking.
- ip status: patented
- sensors: sensor-ppg, sensor-spo2, sensor-ecg, sensor-accelerometer, sensor-barometer
- algorithms: algo-hr, algo-spo2-estimation, algo-afib-detection, algo-arrhythmia-classification, algo-sleep-staging, algo-step-count, algo-respiratory-rate
- prior art notes: Discloses a wristwatch combining reflectance-PPG heart rate, pulse-oximetry SpO2, a single-lead ECG with AF detection, accelerometry, and an altimeter, with sleep-apnea screening (from the SpO2/respiration signals) — multiple regulated cardiorespiratory measurements in one consumer watch. Anticipates multi-modal medical-smartwatch claims reciting combinations of wrist PPG-HR + wrist SpO2 + single-lead ECG from 2020.
