The detected wavelength of perovskite quantum dots embedded in IGZO TFT can be tuned by replacing the quantum dot halogen ions. It is expected that a color-distinguishable artificial human vision system can be developed.

Locust bean gum was utilized to prepare a free-standing quasi-solid-state ZnSO4/MnSO4 electrolyte. Zinc-ion batteries with locust bean gum electrolyte achieved high energy density and superior lifetime.

In this work, we report an active respiration monitoring sensor based on a piezoelectric-transducer-gated thin-film transistor (PTGTFT) aiming to measure respiration-induced dynamic force in real time with high sensitivity and robustness. It differs from passive piezoelectric sensors in that the piezoelectric transducer signal is rectified and amplified by the PTGTFT. Thus, a detailed and easy-to-analyze respiration rhythm waveform can be collected with a sufficient time resolution. The respiration rate, three phases of respiration cycle, as well as phase patterns can be further extracted for prognosis and caution of potential apnea and other respiratory abnormalities, making the PTGTFT a great promise for application in long-term real-time respiration monitoring.
