Overview
- The research team published their results in PNAS and filed a provisional patent for the paintable electrode ink on Monday, July 13, 2026.
- The formulation, called WE‑PPD, is a water‑ethanol mix of PEDOT:PSS, DBSA and polyvinyl alcohol that dries on skin and bonds into a porous silver textile to form a device connection.
- In small laboratory demonstrations the painted electrodes recorded ECG, EMG and EEG signals, including a 12‑hour ECG on a co‑author, a treadmill test that showed 95.1% pre/post‑sweat consistency, and EMG control of a robotic prosthetic.
- Initial safety checks found no skin reactions after 24 hours but the authors emphasize the need for broader toxicity screens and systematic MRI and radiofrequency heating tests before clinical or commercial use.
- The team envisions disposable painted electrodes paired with reusable sensing modules for applications such as pediatric monitoring, robotic interfaces, advanced biomarker sensing and environmental or plant monitoring, with development funded in part by NSF and NIH.
