MEMS microphones from Akustica: a new word in sound processing

13.03.2006

Akustica, which creates "silicon" acoustic components using MEMS technology, has announced the availability of a new product - the AKU2000 single-chip microphone.

The digital signal output device contains a silicon membrane and is well suited for operation in "microphone array" configurations (microphone array) used in cases where a high degree of protection against noise is required. An acoustic transducer, an output amplifier, and a fourth-order sigma-delta modulator are integrated into the crystal. The CMOS process technology is used for manufacturing.

The novelty is designed for surface mounting and should replace the electret condenser microphones (ECM) used for fifty years in millions of portable devices. According to Akustica, its product has a higher noise immunity than EKM.

A huge advantage of using the new microphone compared to existing solutions is the absence of lines through which analog signals are transmitted. This allows designers to position the microphone and other components without worrying about EMC issues.

Samples of the AKU2000 microphone chip can already be ordered for review. The cost of one product in a wholesale lot of 1000 pieces will be $3,87.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

quantum integrated circuit 30.06.2022

Australian developers reported significant progress in the development of quantum computers. Based on almost 20 years of scientific work by Australian teams, a young company from Australia - Silicon Quantum Computing (SQC) - was able to create the world's first quantum integrated circuit. The chip is able to simulate the behavior of just one molecule - polyacetylene, but it does it much better than classical computers.

Designed and manufactured in Sydney, SQC's Quantum Processor is an analog solution for simulating the quantum states of molecules. The company still only dreams of a real quantum processor with the ability to correct errors. But even the molecular simulator promises a breakthrough for the field once such chips are commercially produced.

A quantum chemical compound simulator will help you discover unusual materials and substances for pharmaceuticals and industry. Now we cannot even imagine what properties these materials will have, because such calculations are either impossible on a conventional computer, or will take years, centuries, and even longer as the connections become more complex.

The creation of the first SQC quantum integrated circuit required the implementation of three separate technologies. First, it was necessary to create elements of atomic size so small that their energy levels would equalize, and electrons could easily pass through them. Secondly, it was necessary to implement the possibility of adjusting the energy levels of each element separately, as well as all elements together, in order to control the passage of quantum information.

Finally, it was important to learn how to control the distance between the elements with an accuracy of less than a nanometer, so that the elements remained close enough to each other, but this would not interfere with the quantum coherent transfer of electrons along the chain. All three technological tasks were successfully solved and, as the developers emphasize, this happened two years ahead of schedule.
