A new method for depositing manganese oxide thin-films on planar and complex nanostructured surfaces

Tue, 08/13/2019 - 18:27
Manganese oxides have numerous applications in batteries, supercapacitors, microelectronics and (electro)catalysis. Researchers describe a cheap and fast method for depositing conformal thin films of manganese oxide on nanostructured substrates with close-to-a-monolayer precision, competing with the state-of-the-art atomic layer deposition (ALD). The team's redox layer deposition (RLD) is performed in air, at room temperature, using common and cheap chemicals and simple glassware - literally two beakers.

Moisture-powered, multifunctional flexible sensing systems

Mon, 08/12/2019 - 13:38
Researchers demonstrate the feasibility of an environmental moisture-induced, self-powered wearable multifunctional sensing system with the ability to detect both humidity and pressure. The self-powered wearable sensing system is fabricated by integrating a flexible micropatterned pressure-sensitive film on PET as the pressure sensor and attached it onto the back of a PDA power generator. Test results prove that this moisture-powered sensor can stably and sensitively realize real-time human physiological signal detection.
