A Single‐Stage Differential Amplifier Using Organic Electrochemical Transistors
Advanced Electronic Materials, Volume 11, Issue 9, June 2025.A three‐transistor differential amplifier using depletion‐mode organic electrochemical transistors is implemented that offers a common‐mode rejection ratio of up to ≈20 dB. Compared to a Wheatstone bridge amplifier, ECG recordings with this amplifier showed improved signal‐to‐noise ratio, gain, and power consumption.

Journal of Extracellular Vesicles, Volume 14, Issue 6, June 2025.ABSTRACT Despite remarkable progress in total joint arthroplasty, aseptic loosening of titanium (Ti) alloy persists as a critical clinical challenge due to the poor wear resistance and biological inertness of such implants. Targeting of inflammatory osteolysis and remodelling of the osseointegration environment represent promising therapeutic ...
