Nature Communications, Journal Year: 2018, Volume and Issue: 9(1)

Published: Jan. 10, 2018

Mechanosensation electronics (or Electronic skin, e-skin) consists of mechanically flexible and stretchable sensor networks that can detect quantify various stimuli to mimic the human somatosensory system, with sensations touch, heat/cold, pain in skin through sensory receptors neural pathways. Here we present a skin-inspired highly conformable matrix network (SCMN) successfully expands e-skin sensing functionality including but not limited temperature, in-plane strain, humidity, light, magnetic field, pressure, proximity. The actualized specific expandable units integrated on structured polyimide network, potentially three-dimensional (3D) integration scheme, also fulfill simultaneous multi-stimulus achieve an adjustable range large-area expandability. We further construct personalized intelligent prosthesis demonstrate its use real-time spatial pressure mapping temperature estimation. Looking forward, this SCMN has broader applications humanoid robotics, new prosthetics, human-machine interfaces, health-monitoring technologies.

Wearable smart sensor systems integrated on soft contact lenses for wireless ocular diagnostics

Nature Communications, Journal Year: 2017, Volume and Issue: 8(1)

Published: April 27, 2017

Abstract Wearable contact lenses which can monitor physiological parameters have attracted substantial interests due to the capability of direct detection biomarkers contained in body fluids. However, previously reported lens sensors only a single analyte at time. Furthermore, such ocular generally obstruct field vision subject. Here, we developed multifunctional sensor that alleviates some these limitations since it was on an actual lens. It also designed glucose within tears, as well intraocular pressure using resistance and capacitance electronic device. in-vivo in-vitro tests live rabbit bovine eyeball demonstrated its reliable operation. Our measure level tear fluid simultaneously but yet independently based different electrical responses.
