PEDOT‐Based Eutectogel Electrode Arrays for Enhanced High‐Resolution Electrogastrography: Fabrication, Stability, and Wearable Performance

Advanced Functional Materials, EarlyView.
Here, we present a high‐density PEDOT eutectogel electrode array for enhanced body surface gastric mapping. Silver electrodes are blade‐coated onto flexible substrates, followed by electrogelation of PEDOT:PSS and the deposition of a PEDOT:LS eutectogel.

Passive control of sonic flow from converging nozzle with D-shaped rib

Results in Engineering
The abrupt expansion at the blunt base of projectiles, rockets, missiles, etc., is a common phenomenon. Flow separation and reattachment are caused by the abrupt increase in the base area, and the pressure in the separated recirculation area is lower ...
