'Electronic skin' from bio-friendly materials can track human vital signs with ultrahigh precision

Researchers have used materials inspired by molecular gastronomy to create smart wearables that surpassed similar devices in terms of strain sensitivity. They integrated graphene into seaweed to create nanocomposite microcapsules for highly tunable and sustainable epidermal electronics. When assembled into networks, the tiny capsules can record muscular, breathing, pulse, and blood pressure measurements in real-time with ultrahigh precision.

Nanomaterials: 3D printing of glass without sintering

A new process enables printing of nanometer-scale quartz glass structures directly onto semiconductor chips. A hybrid organic-inorganic polymer resin is used as feedstock material for 3D printing of silicon dioxide. Since the process works without sintering, the required temperatures are significantly lower. Simultaneously, increased resolution enables visible-light nanophotonics.

A novel completely solid rechargeable air battery

Solid-state batteries use solid electrodes and solid electrolytes, unlike the more commonly known lithium-ion batteries, which use liquid electrolytes. Solid-state batteries overcome various challenges associated with liquid-based batteries, such as flammability, limited voltage, unstable reactants, and poor long-term cyclability and strength. Making advances in this field, researchers recently demonstrated an all-solid-state rechargeable air battery composed of a redox-active organic negative electrode and a proton-conductive polymer electrolyte.

'Heat highways' could keep electronics cool

As smart electronic devices become smaller and more powerful, they can generate a lot of heat, leading to slower processing times and sudden shutdowns. Now researchers use an electrospinning approach to produce a new nanocomposite film. In tests, the film dissipated heat four times more efficiently than similar materials, showing that it could one day be used to keep electronics cool.
