Bioactive inks printed on wearable textiles can map conditions over the entire surface of the body

Posted by in categories: biotech/medical, chemistry, health, wearables

Researchers at Tufts University’s School of Engineering have developed biomaterial-based inks that respond to and quantify chemicals released from the body (e.g. in sweat and potentially other biofluids) or in the surrounding environment by changing color. The inks can be screen printed onto textiles such as clothes, shoes, or even face masks in complex patterns and at high resolution, providing a detailed map of human response or exposure. The advance in wearable sensing, reported in Advanced Materials, could simultaneously detect and quantify a wide range of biological conditions, molecules and, possibly, pathogens over the surface of the body using conventional garments and uniforms.

“The use of novel bioactive inks with the very common method of screen printing opens up promising opportunities for the mass-production of soft, wearable fabrics with large numbers of sensors that could be applied to detect a range of conditions,” said Fiorenzo Omenetto, corresponding author and the Frank C. Doble Professor of Engineering at Tufts’ School of Engineering. “The fabrics can end up in uniforms for the workplace, sports clothing, or even on furniture and architectural structures.”

A system for the nonreciprocal transmission of microwave acoustic waves

Posted by in categories: computing, electronics

Acoustic waves have been found to be highly versatile and promising carriers of information between chip-based electronic devices. This characteristic is ideal for the development of a number of electronic components, including microwave filters and transducers.

In the past, some researchers have tried to build devices in which waves are transmitted between two ports in a non-symmetric way. These are known as nonreciprocal devices. These devices could be particularly promising for the manipulation and routing of phonons, quasiparticles associated with . Building nonreciprocal devices that transmit acoustic waves, however, can be highly challenging, as typically transmit waves in a linear way.

Researchers at Harvard University have recently achieved the non-reciprocal transmission of non-reciprocal acoustic waves using a nonlinear parity-time symmetric system. This system, presented in a paper published in Nature Electronics, is based on two coupled acoustic resonators placed on a lithium niobate surface.

Black holes are like a hologram

Posted by in categories: cosmology, holograms, quantum physics

The theory of relativity describes black holes as being spherical, smooth and simple. Quantum theory describes them as being extremely complex and full of information. New research now proposes a surprising solution to this apparent duality.

Physicists create quantum-inspired optical sensor

Posted by in categories: biological, information science, quantum physics, space

Researchers from the Moscow Institute of Physics and Technology, joined by a colleague from Argonne National Laboratory, U.S., have implemented an advanced quantum algorithm for measuring physical quantities using simple optical tools. Published in Scientific Reports, their study takes us a step closer to affordable linear optics-based sensors with high performance characteristics. Such tools are sought after in diverse research fields, from astronomy to biology.

Maximizing the sensitivity of measurement tools is crucial for any field of science and technology. Astronomers seek to detect remote cosmic phenomena, biologists need to discern exceedingly tiny organic structures, and engineers have to measure the positions and velocities of objects, to name a few examples.

Until recently, no measurement could ensure precision above the so-called shot noise limit, which has to do with the statistical features inherent in classical observations. Quantum technology has provided a way around this, boosting precision to the fundamental Heisenberg limit, stemming from the basic principles of quantum mechanics. The LIGO experiment, which detected for the first time in 2016, shows it is possible to achieve Heisenberg-limited sensitivity by combining complex optical interference schemes and quantum techniques.

A look at Tesla battery degradation and replacement after 400,000 miles

Posted by in categories: life extension, sustainability

In this new installment of our series on the highest-mileage Tesla Model X (and one of the highest mileage EVs in the world), we look into battery degradation and replacement on a Tesla with over 400,000 miles.

Earlier this year, I bought one of the cheapest and most high-mileage Tesla Model X vehicles ever.

Fiat Introduces All-Electric E-Ducato Van

Posted by in category: transportation

FCA’s commercial vehicle arm Fiat Professional presents the production version of its all-electric Ducato van, the Fiat E-Ducato, a year after the first prototype was shown in mid-2019. It will be the first electric Ducato in the 39-year history of the model.

It’s expected to enter the European market within the next few months, starting from selected countries, and will be available in all body variants, offering a payload of up to 1,950 kg and load volume from 10 to 17 m3.
