Moisture-powered, multifunctional flexible sensing systems

NanoWerk.com - 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.

Scientists can now control thermal profiles at the nanoscale

ScienceDaily.com: Nanotechnology News - Sat, 08/10/2019 - 01:08
Scientists have designed and tested an experimental system that uses a near-infrared laser to actively heat two gold nanorod antennae to different temperatures. The nanorods are so close together that they are both electromagnetically and thermally coupled. Yet the team measured temperature differences between the rods as high as 20 degrees Celsius and could change which nanorod was cooler and which was warmer, even though the rods were made of the same material.
