New Spectral Sensing Technology for Detection of COVID-19

General Description of AS7341L

AS7341L is a 10-channel spectrometer for spectral identification and analytic applications used in mobile devices. The spectral response is defined in the wavelengths from approximately 350nm to 1000nm. 6 channels can be processed in parallel by independent ADCs while the other channels are accessible via a multiplexer. 8 optical channels cover the visible spectrum, one channel can be used to measure near infra-red light and one channel is a photodiode without filter ("clear"). The NIR channel in combination with the other VIS channels may provide information about special characteristics of analytes (e.g. Lateral Flow Tests).  The device can also be synchronized to external signals via pin GPIO. 


                                                Ams Semiconductor AS7341L Spectral Sensor Solution

AS7341L integrates filters into standard CMOS silicon via Nano-optic deposited interference filter technology and its package provides a built-in aperture to control the light entering the sensor array. Control and Spectral data access are implemented through a serial I²C interface. The device is available in an ultra-low profile package with dimensions of 3.1mm x 2mm x 1mm. 

Optical measurement technology company ELDIM has chosen to use Ams Semiconductor's spectral sensing technology for rapid, professional detection of COVID-19 (SARS-COV-2)

Ams AG provides the latest sensor technology to ELDIM, a French provider of optical measurement technology and related software and hardware design. And to help develop a testing solution for COVID-19 (SARS-COV-2) instant care applications -- a solution that uses molecular biology techniques to obtain results in about 40 minutes when used in a professional medical environment -- previously, such tests often took hours or days.

The AS7341L spectral sensor solution based on Ams Semiconductor specifically developed a sensor system that uses the spectrum to parse and read amplified RNA from virus particles. This system further strengthens the position of Ams Semiconductor in providing high-quality professional health diagnostics.


Optical measurement technology uses light to determine measurement unit standards and other standards for high-precision research. A team of several companies and institutions has been actively studying the project for several months. They include Loop Dee Science, a biotechnology start-up that focuses on instant care testing; LRX Technologies, a designer of tiny interconnected optical sensors; ELDIM, an industrial reader maker; and CHU Caen University Hospital in Normandy, which provides scientific advice and clinical supervision. All of these institutions are located in Normandy, France. Eventually, the LoopXplore COVID-19 analysis suite and the Portable automated diagnostic professional LoopX were successful.

Realization of Miniaturization of PCR Detection in Professional Medical Environment

PCR (polymerase chain reaction) testing is the basis for most of the genetic tests currently performed and is the most commonly used test method for COVID-19 (SARS-COV-2). However, the equipment used and the expertise required to interpret the data are highly specialized, expensive, and can only be done in centralized laboratories. By contrast, the new method offered by ELDIM and its partners uses thermostatic amplification to detect the virus itself, eliminating the need for cumbersome equipment. The advantage of this method is that patients can get almost immediate accurate test results of their own health status, thus avoiding the spread of the virus.

Working Together to Improve COVID-19 Health Outcomes

"Combining ELDIM's high-precision engineering and design capabilities with partner's technology and clinical advice, coupled with Ams AG Semiconductor's high-performance and highly sensitive spectral sensors, resulted in a micro-detection method. It is faster and more flexible than PCR and still has the same accuracy," said Pascal Philippon, senior vice president of Sales and Marketing for Ams Semiconductor Europe, Middle East and Africa.

"ELDIM is committed to supporting start-ups in developing new projects across a wide range of industries. During the implementation of this important project, we were responsible for overseeing the sensor and analysis components of the LoopX solution. Our proven experience in high-end, mass production processes and manufacturing capabilities will bring superior detection accuracy to healthcare facilities and reliability to future customers." said Thierry Leroux, President and CEO of ELDIM.

The introduction and application of audio amplifier

-
Image
With the continuous changes in the audio market demand, the audio amplifier design structure has made great progress. When selecting the best audio amplifier IC for a specific application, it is important to have a full understanding of the types of audio amplifiers available and their characteristics. The audio amplifier increases the amplitude of a small signal to a useful level while retaining the details of the small signal, which is called linearity. The better the linearity of the amplifier, the more true the output signal can represent the input signal. As the audio market's requirements for amplifier performance continue to change, audio amplifier circuit structures have made great progress. Therefore, the designer must understand the available audio amplifiers and their characteristics. This is the only way to ensure that the best audio amplifier is selected. In this article, we introduce the most important features of the various audio amplifiers available today: Class A,...

Precautions when using the force sensor

-
Image
Although the force sensor has the characteristics of solidarity and durability, there are still some problems we should pay attention to when it is used.  1. protecting the force sensor from contamination caused by the external environment We should try to set up some "baffles" around the force sensor, and even cover the force sensor with a thin metal plate. This can prevent debris from contaminating the force sensor and certain movable parts, and this "contamination" often affects the weighing accuracy. 2. the connection of the shielding wire and the grounding point should be reasonable All wires leading to or from the display circuit should adopt shielding cables. The connection and grounding point of the shielded wire should be reasonable. If it is not grounded through the mechanical frame, it is grounded externally. 3. avoiding strong heat radiation The force sensor should use hinged copper wires (cross-sectional area of ​​about  50mm 2 ) to form an electrical b...

IRF640 vs IRF740: What is the difference?

-
Image
MOSFET Explained / Description IRF740 is a high voltage N channel MOSFET, the transistor is basically designed for high voltage and high-speed switching applications. The max load voltage this transistor can drive is up to 400V with a maximum load current of 10A. The maximum current in pulse mode is 40A and the on-resistance or (RDS) is 0.55 ohms. The max drain to source voltage of 400V makes it ideal to drive a variety of high voltage loads in electronic circuits.   IRF640 is an N Channel MOSFET designed for high-speed switching purposes. This high-speed switching capability can be very useful in applications where switching speed is crucial, for example in a UPS circuit or in any other application where the user wants to change the load input power from one source to another. The transistor is capable of driving a load of up to 18A and the voltage can be up to 200V with the minimum saturation voltage of only 2V to 4v at its gate. The pulsed drain current is 72A means this MOSFET ...
