Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Flexible 32-bit ARM microcontroller 24.07.2021

Unlike conventional semiconductor chips, flexible electronic devices are based on paper, plastic, or foil substrates and use active thin-film semiconductor materials, including organic compounds, metal oxides, and amorphous silicon.

After six years of development, ARM introduced the first fully 32-bit flexible PlasticARM microcontroller, which consists of 56 thin-film NMOS transistors (Negative channel Metal-Oxide-Semiconductor) and resistors on a plastic substrate provided by the British manufacturing company PragmatIC Semiconductor from Cambridge.

The chipset is implemented using the 0,8 micron PragmatIC process and standard tooling. It consists of four metal layers on a 200 mm polyimide plate. The two lower layers contain standard cells, and the two upper ones serve to connect them. This approach made it possible to bring the total valve density to approximately 300 per mm2.

At 59,2 square millimeters, PlasticARM is 12 times the size of a previous joint development between ARM and PragmatIC - a dedicated FlexIC core for machine learning workloads - and marks a significant step forward in low-cost, flexible plastic electronics for everyday IoT-connected objects.

As reported in an article published yesterday by the journal Nature, the flexible microcontroller includes a 32-bit CPU, NVIC (Nested Vector Interrupt Controller) for handling interrupts from external devices, peripherals, memory and interface, an AHB-lite interconnect bus and 456 bytes ROM. The firmware contains three test programs using the ARMv6-M instruction set and the standard ARM toolchain.

The entire system-on-a-chip (SoC) runs at 29kHz from a 21V power supply and draws 45mW, of which the processor accounts for 33%, memory for 22%, and peripherals for the remaining XNUMX%.

The main problem associated with plastic was energy consumption and heat dissipation. ARM's low-power cell libraries are predicted by ARM's engineers to be capable of supporting plastic chips with a complexity of around 100 gates (this will allow more peripherals to be used with the controller core). A million or more logic gates will likely require Complementary Metal Oxide Semiconductor (CMOS) technology.
