Yao et al. (Parviz group) (2011) — contact lens with embedded electrochemical sensor for tear glucose (2011-03-15)
- id:
yao-parviz-2011-contact-lens-glucose-sensor - corpus: academic
- form factor: contact-lens
- creator: Hung Yao / Babak A. Parviz et al. (University of Washington)
- disclosure: Yao H, Shum AJ, Cowan M, Lähdesmäki I, Parviz BA. ‘A contact lens with embedded sensor for monitoring tear glucose level.’ Biosensors and Bioelectronics 2011;26(7):3290-3296.
- ip status: public-domain
- sensors: sensor-glucose-cgm, sensor-optical-glucose
- algorithms: algo-glucose-noninvasive
- prior art notes: Discloses a soft contact lens with an embedded amperometric glucose-oxidase electrochemical sensor and integrated interconnects to measure glucose in the tear film — a corneal-contact noninvasive glucose monitor. Anticipates contact-lens biosensor claims combining ‘a soft ophthalmic contact lens’, ‘an embedded electrochemical sensor at the lens surface’, and ‘detection of an analyte in the tear film (glucose)’ from 2011. Anchor for the contact-lens × biosensor cross-cut on the real side; relevant to [[rainbows-end-ar-contact-lens]] (the fictional AR-lens antecedent) and to the Google/Verily ‘smart contact lens’ patent estate.
Google[X] / Verily smart contact lens (2014) — tear-glucose-sensing contact lens project (2014-01-16)
- id:
verily-google-smart-contact-lens-2014 - corpus: private
- form factor: contact-lens
- creator: Google[X] / Verily Life Sciences (Brian Otis, Babak Parviz, et al.)
- disclosure: Google[X] (Brian Otis, Babak Parviz). ‘Smart contact lens’ project, publicly disclosed 16 January 2014 — a soft contact lens with an embedded miniature glucose sensor, antenna, and wireless interface to a phone, intended to continuously measure tear glucose. Later transferred to Verily (Alphabet’s life-sciences arm) and licensed to Novartis/Alcon; the program was reported wound down c. 2018 without a shipping product, but the underlying patent estate (Otis et al., Parviz et al.; e.g. US 8,608,310; US 9,184,698 and continuations) is extensive.
- ip status: patented
- sensors: sensor-glucose-cgm, sensor-optical-glucose
- algorithms: algo-glucose-noninvasive
- prior art notes: Discloses a soft contact lens with an embedded miniature electrochemical glucose sensor, antenna, and wireless interface for continuous tear-glucose monitoring — a major industrial follow-on to [[yao-parviz-2011-contact-lens-glucose-sensor]]. Anticipates smart-contact-lens claims combining ‘a soft ophthalmic lens’, ‘an embedded biosensor’, and ‘wireless transmission of the sensed analyte’ from 2014; the extensive associated patent family is itself prior art on most subsequent contact-lens-biosensor and embedded-lens-electronics claims. Product-side anchor for the contact-lens × biosensor cross-cut.
Bandodkar et al. (2015) — tattoo-based noninvasive glucose monitoring (2014-12-12)
- id:
bandodkar-2015-tattoo-glucose-sensor - corpus: academic
- form factor: tattoo-electronic
- creator: Amay J. Bandodkar / Joseph Wang group (UC San Diego)
- disclosure: Bandodkar AJ, Jia W, Yardımcı C, Wang X, Ramirez J, Wang J. ‘Tattoo-based noninvasive glucose monitoring: a proof-of-concept study.’ Analytical Chemistry 2015;87(1):394-398.
- ip status: public-domain
- sensors: sensor-glucose-cgm
- algorithms: algo-glucose-noninvasive
- prior art notes: Discloses a temporary-tattoo-format epidermal device that uses reverse iontophoresis to extract interstitial fluid through the skin and amperometric enzyme electrodes to measure glucose in it, demonstrating noninvasive transdermal glucose monitoring without a needle. Anticipates noninvasive-CGM claims combining ‘a skin-mounted tattoo/epidermal patch’, ‘iontophoretic extraction of interstitial fluid’, and ‘electrochemical glucose measurement at the skin surface’ from 2015. Anchor for the tattoo-electronic × glucose-CGM cross-cut on the real side; relevant to [[koh-rogers-2016-soft-microfluidic-sweat-device]] and the broader [[bandodkar-wang-2014-wearable-electrochemical-sensors-review]].
