Stretchable, degradable semiconductors

ScienceDaily.com: Nanotechnology News - Wed, 11/13/2019 - 17:30
To seamlessly integrate electronics with the natural world, materials are needed that are both stretchable and degradable -- for example, flexible medical devices that conform to the surfaces of internal organs, but that dissolve and disappear when no longer needed. However, introducing these properties to electronics has been challenging. Now, researchers have developed stretchable, degradable semiconductors that could someday find applications in health and environmental monitoring.

New research finds carbon nanotubes show a love/hate relationship with water

NanoWerk.com - Tue, 11/12/2019 - 22:21
New research reveals that carbon nanotubes (CNTs) as a coating can both repel and hold water in place, a useful property for applications like printing, spectroscopy, water transport, or harvesting surfaces. When water is dropped on a CNT forest, the CNTs repel the water, and it forms a sphere. However, when flipped over, the drop does not fall to the ground but rather clings to the surface.

Enhancing wireless in vivo sensor readouts with 'divergent exceptional points'

NanoWerk.com - Tue, 11/12/2019 - 15:01
Radio-frequency wireless sensors are essential components of smart objects and internet-of-things components. However, these passive microsensors suffer from poor quality of data and sensitivity due to the environments they operate in and the need for sensors with extremely small footprints. Researchers have recently shown that a wireless system locked to an exceptional point (EP) can enhance the sensitivity of passive wireless sensors in practical applications. New work has theoretically introduced and experimentally demonstrated a new class of parity-time-symmetric RF electronic and telemetric systems, which combine EPs with divergent points.

Biodegradable microresonator implants for medical applications

NanoWerk.com - Mon, 11/11/2019 - 18:16
The goal of the electronics industry has always been to build durable devices with stable performance that last a very long time. 'Transient electronics', however, are designed with the exact opposite goal: to dissolve harmlessly into their surroundings after functioning for a certain amount of time. The fabrication process and the in vivo powering of medical implants that are only made from biodegradable materials are two of the challenges associated with transient electronics. Researchers demonstrate wirelessly powered, frequency-selective magnesium microstructures as promising candidates to be used as power receiver, microheaters and triggering elements for biodegradable implantable medical devices.
