Highlighted research relevant to wearables at Stanford University

Wearable organic electrochemical transistor (OECT) sensor patch for human perspiration

Prof. Alberto Salleo et al report the integration of ammonium and calcium ion‐selective membranes with an OECT for multiplexed sensing of NH4+ and Ca2+ in sweat with high sensitivity and selectivity.

Polymer chemistries underpinning materials for skin-inspired electronics

Prof. Zhenan Bao et al discuss chemistry that can enable self-healing, stretchable/elastic, conformal, transient, and/or adhesive functionality in future wearable devices.

Multi-scale ordering in highly stretchable polymer semiconducting films

Prof. Zhenan Bao, Prof. Boris Murmann et al report a solution processing approach that may serve as the basis for large-area manufacturing of stretchable semiconducting films.

A wireless body area sensor network (bodyNET) based on stretchable passive tag

Prof. Zhenan Bao et al report a bodyNET composed of chip-free and battery-free stretchable on-skin sensor tags that are wirelessly linked to flexible readout circuits attached to textiles.

Temperature regulation in colored infrared-transparent polyethylene textiles

Prof. Yi Cui et al report the first demonstration of colored polyethylene textiles with high IR transparency for radiative cooling.

Low-voltage high-performance flexible digital and analog circuits based on ultrahigh-purity semiconducting carbon nanotubes

Zhenan Bao et al demonstrate a tunable-gain amplifier, ring oscillators, and shift registers using carbon nanotube thin film transistors.

Direct measurement of swimming and diving kinematics of giant Atlantic bluefin tuna

Prof. Barbara Block et al use data-logging tags on tuna to determine that versatility of swimming gaits and diving behaviors reduce unnecessary energy expenditure and help to regulate body temperature.

Modular and reconfigurable stretchable electronic systems

Prof. Zhenan Bao et al demonstrate novel applications of tough, self-healing elastomer to realize skin-like modular electronics systems, in which multiple electronic components are electrically interconnected, can be reconfigured, and can communicate with each other digitally.
