Neon Genesis Evangelion — ‘plug suit’ and ‘A10 nerve clips’ (bio-monitoring suit + head-worn neural sync interface) (1995-10-04)
- id:
nge-plug-suit-and-a10-clips - corpus: fictional
- form factor: garment
- creator: Hideaki Anno / Gainax
- disclosure: Neon Genesis Evangelion (Gainax television series, premiered 4 October 1995); pilots wear a skin-tight pressurized ‘plug suit’ with continuous bio-monitoring and a measured ‘synchronization ratio’ with the mecha, plus ‘A10 nerve clips’ worn on the head that interface the pilot’s nervous system to the machine.
- ip status: fictional
- sensors: sensor-ecg, sensor-dry-eeg-electrode, sensor-respiration-impedance
- algorithms: algo-hr, algo-respiratory-rate
- prior art notes: Discloses (a) a form-fitting body garment with continuous vital-sign monitoring and a derived operator-machine synchronization metric, and (b) head-worn clips coupling the wearer’s nervous system to an external system. Relevant to instrumented-bodysuit claims combining ‘a close-fitting garment with distributed physiological sensors’ and ‘a derived synchronization/engagement metric’, and to head-worn neural-interface claims. § 103 motivation as of 1995. Cf. [[pacific-rim-drivesuit-and-conn-pod]] (a later dual-pilot variant).
Paradiso et al. (2005) — ‘A wearable health care system based on knitted integrated sensors’ (WEALTHY) (2005-09)
- id:
paradiso-2005-wealthy-knitted-smart-shirt - corpus: academic
- form factor: garment
- creator: Rita Paradiso / Giannicola Loriga / Nicola Taccini (Smartex / CNR, Italy; EU WEALTHY consortium)
- disclosure: Paradiso R, Loriga G, Taccini N. ‘A wearable health care system based on knitted integrated sensors.’ IEEE Transactions on Information Technology in Biomedicine 2005;9(3):337-344. (Output of the EU FP5 ‘WEALTHY’ project, 2002-2005.)
- ip status: public-domain
- sensors: sensor-ecg, sensor-respiration-impedance, sensor-piezoelectric, sensor-accelerometer, sensor-skin-temperature
- algorithms: algo-hr, algo-respiratory-rate, algo-activity-classification
- prior art notes: Discloses a smart shirt with electrodes and sensors knitted directly into the textile (conductive yarns forming dry ECG electrodes; piezoresistive yarns forming respiration sensors via thoracic/abdominal expansion; accelerometer; temperature) plus an on-garment electronic interface and wireless link, deriving ECG, heart rate, respiration, posture/activity, and temperature — i.e. a fully integrated textile-electrode wearable. Any claim reciting ‘an item of clothing with electrodes/sensors integrated into the fabric structure for physiological monitoring’ reads on Paradiso 2005. Anchor for the garment × textile-electrode cross-cut; the foundational EU project for the smart-shirt patent space (Hexoskin, Cityzen, etc. all build on this lineage).
Pantelopoulos & Bourbakis (2010) — survey on wearable sensor-based systems for health monitoring and prognosis (2010-01)
- id:

- form factor: other
- creator: Alexandros Pantelopoulos / Nikolaos G. Bourbakis
- 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.
Hexoskin smart shirt (2014) — textile-integrated ECG, respiration and activity garment (2013)
- id:
hexoskin-smart-shirt-2014 - corpus: private
- form factor: garment
- creator: Carre Technologies Inc.
- disclosure: Carre Technologies Inc. (Hexoskin). ‘Hexoskin Smart Shirt’, introduced 2013 (consumer); a compression shirt with knitted dry textile electrodes for single-lead ECG, two-channel respiratory inductive plethysmography (thoracic + abdominal expansion), a 3-axis accelerometer, and a removable electronics pod, deriving HR, HRV, breathing rate/volume, cadence, steps, and sleep. (Used in NASA/CSA ‘Astroskin’ studies.)
- ip status: patented
- sensors: sensor-ecg, sensor-respiration-impedance, sensor-piezoelectric, sensor-accelerometer
- algorithms: algo-hr, algo-hrv, algo-respiratory-rate, algo-activity-classification, algo-sleep-staging
- prior art notes: Discloses a consumer/research compression shirt with textile-integrated dry ECG electrodes, two-channel respiratory inductive plethysmography (thoracic + abdominal), an accelerometer, and a removable electronics pod, deriving HR, HRV, breathing rate and volume, activity, and sleep. A commercial realization of [[paradiso-2005-wealthy-knitted-smart-shirt]]; anticipates smart-shirt claims combining ‘textile-integrated ECG and respiration sensors’ and ‘a detachable electronics module’ from 2013. Product-side anchor for the garment × textile-electrode cross-cut.
