Real-time measurement of electrolytes and metabolites could be used to diagnose and monitor disease or track performance. Engineers at Tufts University have created a first-of-its-kind flexible electronic sensing patch that can be sewn into clothing to analyze your sweat for multiple markers. The patch could be used to to diagnose and monitor acute and chronic health conditions or to monitor health during athletic or workplace performance. The device, described today in the journal NPJ Flexible Electronics, consists of special sensing threads, electronic components and wireless connectivity for real time data acquisition, storage and processing.

Typical consumer health monitors can track heart rate, temperature, glucose, walking distan...

A recently published study led by Virginia Commonwealth University researchers sheds new light on how water interacts with the nanomaterial graphene, a single, thin layer of carbon atoms arranged in a hexagonal honeycomb lattice.

The researchers’ findings could hold implications for a variety of applications, including sensors, fuel cell membranes, water filtration, and graphene-based electrode materials in high-performance supercapacitors.

The study, “Solvent–Solvent Correlations across Graphene: The Effect of Image Charges,” was published in the American Chemica...

Researchers can now grow twistronic material at sizes large enough to be useful. While an exciting potential area of nanotechnology, twistronics until now has mostly been explored on samples smaller than human hairs. Now researchers can produce samples on the centimetre scale.

2D materials, which consist of a single layer of atoms, have attracted a lot of attention since the isolation of graphene in 2004...

Interconnected healthcare and many other future applications will require internet connectivity between billions of sensors. The devices that will enable these applications must be small, flexible, reliable, and environmentally sustainable. Researchers must develop new tools beyond batteries to power these devices, because continually replacing batteries is difficult and expensive.

In a study published in Advanced Materials Technologies, researchers from Osaka University have revealed how the thermoelectric effect, or converting temperature differences into electricity, can be optimally used to power small, flexible devices...
