Energy Harvester Produces Power from Local Environment, Eliminating Batteries in Wireless Sensors

Posted by in categories: robotics/AI, transportation

Advances in low power technology are making it easier to create wireless sensor networks in a wide range of applications, from remote sensing to HVAC monitoring, asset tracking and industrial automation. The problem is that even wireless sensors require batteries that must be regularly replaced—a costly and cumbersome maintenance project. A better wireless power solution would be to harvest ambient mechanical, thermal or electromagnetic energy from the sensor’s local environment.

Typically, harvestable ambient power is on the order of tens of microwatts, so energy harvesting requires careful power management in order to successfully capture microwatts of ambient power and store it in a useable energy reservoir. One common form of ambient energy is mechanical vibration energy, which can be caused by motors running in a factory, airflow across a fan blade or even by a moving vehicle. A piezoelectric transducer can be used to convert these forms of vibration energy into electrical energy, which in turn can be used to power circuitry.

WHO declares rapidly spreading monkeypox outbreak a global health emergency

Posted by in categories: biotech/medical, health

Tedros said the risk posed by monkeypox is moderate globally, but the threat is high in Europe. There’s clearly a risk that the virus will continue to spread around the world, he said, though it’s unlikely to disrupt global trade or travel right now.

In early May, the United Kingdom reported a case of monkeypox in a person who recently returned from travel to Nigeria. Several days later, the U.K. reported three more cases of monkeypox in people who appeared to have become infected locally. Other European nations, Canada and the U.S. then also began confirming cases. It’s unclear where the outbreak actually began.

The WHO last issued a global health emergency in January 2020 in response to the Covid-19 outbreak and two months later declared it a pandemic. The WHO has no official process to declare a pandemic under its organizational laws, which means the term is loosely defined. In 2020, the agency declared Covid a pandemic in an effort to warn complacent governments about the “alarming levels of spread and severity” of the virus.

How quantum batteries could lead to million-mile EVs

Posted by in categories: quantum physics, sustainability

The automotive industry has a ‘million-mile’ dream for electric vehicles, but it’s a boring one. They want to build a battery capable of being recharged over and over as many times as it takes to reach a million miles without losing its ability to retain a charge. Yawn.

We’re more interested in the cutting-edge quantum physics version of a million-mile battery: one that can last a million miles between charges.

This would effectively eliminate the need for the bulk of vehicle operators to ever charge their batteries. Even heavy-use owners could just pop into the shop for routine maintenance every couple of years to top their batteries off.
