Micro-mass sensors can be used for the detection of gases, organic cells, viruses and bacteria in a system. With today's growing need for immediate virus detection systems such as COVID-19, micro-mass sensors have become a viable and attractive option. As a demonstration of the capabilities of this sensor, an operational model has been developed for CO2 molecules, being the same system that could be used for other types of applications.
The microfabrication process used to the development of this systems opens new opportunities for the development of highly integrated microsensors, with lower energy consumption, foot-print, and fabrication costs than the actual technology.
The final product can be considered as a preindustrial product that with a few adaptions can be ...
Avalanche photodiodes (APD's) offer increased sensitivity over photodiodes. Applications such as Lidar and fiber optic communications experience significant performance improvements by taking advantage of the higher sensitivity afforded by APD's.
However, APD's require a high voltage bias of ~50V to 600V or higher. Current bias power supply options are often too bulky, heavy and expensive for practical use in high volume applications and size constrained systems such as automotive or drone Lidar imaging.
Start-up power supply company Mike Doherty Designs, LLC, a Colorado Corporation, has targeted this market and has developed a miniature, very low cost design with a suite of APD specific features otherwise unavailable in the marketplace.
Despite its small size and low cost, this line of ...
As per title the power to run the sensor can be generate using Biomass and Bacterial colony.
There are several species of bacteria that can produce Bio-gas to generate power for sensors.
To produce biogas or power, these bacterial colony will be depend on liquid of leaves of tree, grass. The liquid can be obtained by just crushing the leaves and grass. As per sketch just infuse the liquid gained from tree leaves or grass into the Vial filled with bacterial colony as a food for bacterial colony and the colony will work to provide power in the form of gas. This gas can be used directly to powering the sensor or as a fuel cell. I know there ...
Catastrophic failure concerns of Li-ion batteries including excessive heating, fires and explosions create anxiety in battery consumer markets, especially as larger and more powerful Li-ion battery architecture hits the marketplace.
The main cause of failure is the internal short-circuit, which causes thermal runaway and ignition of the battery flammable materials.
Available methods to detect expected battery failure are not precise, costly, and time-consuming requiring days, weeks or even months. Internal shorts significantly increase normal cell leakage (self-discharge) which can be used as a metric for short detection and catastrophic failure prediction.
INL’s Battery Health Sentry is a simple and accurate technique for rapidly detecting internal shorts via fast measurement of self-discharge current in lithium-ion batteries.
The method involves connecting ...
How do blind person read? Currently, there are two major options or category for a blind person to read books. The first one is using Braille imprinted on paper. It is one of the oldest and universally accepted systems of writing used by and for blind persons and consisting of a code of 63 characters, each made up of one to six raised dots arranged in a six-position matrix or cell. These Braille characters are embossed in lines on paper and read by passing the fingers lightly over the manuscript. The second one focus on audio conversion of text via AI. Non blind person can able to enjoy reading in public with his or her tablet just by installing ...

Silicon on Demand  is a novel, patented, and low-cost process for printing large numbers of small regions of single-crystal silicon on large area substrates. The process makes use of well-established semiconductor industry technologies. For ...
Instead of walking to the mail box and finding it empty, or not yet delivered, have a mail box sensor that detects opening, and change inbox volume, and sends notification to a smart phone. The sensor would be battery operated, and should last two years.
The notification would be "mail ...
