Abstract
A wearable device may include a sensor. The sensor may include a flexible fabric, a conjugated polymer coating deposited on the fabric via vapor-phase oxidative chemical vapor deposition (oCVD), and a plurality of electrodes in coupled to the conjugated polymer coating. The wearable device may further include a processor communicatively coupled to the electrodes. The processor may measure an electrical property across the electrodes, determine a physiological event based on the measured electrical property, and output measurement information corresponding the physiological event.
Claims15
A wearable device comprising:
- a sensor comprising,
- a flexible fabric;
- a poly(3,4-ethylenedioxythiophene) (PEDOT) coating conformally deposited on the fabric via vapor-phase oxidative chemical vapor deposition (oCVD) wherein deformation of the fabric causes a resistance change in the PEDOT coating, and
- a plurality of electrodes coupled to the PEDOT coating;
- and
- a processor communicatively coupled to the electrodes, the processor configured to:
- measure an electrical property across the electrodes;
- and
- determine a physiological event based on the measured electrical property caused by the deformation of the fabric and the resistance change of the PEDOT coating;
- and
- output measurement information corresponding to the physiological event.
A wearable article, comprising:
- a sensor comprising,
- a flexible fabric;
- a poly(3,4-ethylenedioxythiophene) (PEDOT) coating conformally deposited on the fabric via vapor-phase oxidative chemical vapor deposition (oCVD) such that deformation of the fabric causes a resistance change in the coating, and
- a plurality of electrodes coupled to the conjugated polymer coating.
