Processor based on 2D molybdenum disulfide transistors

22.11.2023

A research team from the École Polytechnique Federale de Lausanne (EPFL) has unveiled an innovative processor based on atomically thin molybdenum disulfide (MoS2) semiconductors. This 1024-transistor processor offers a new approach to computing by storing data within the processor and significantly reducing computer power consumption.

The unveiled molybdenum disulfide processor with integrated in-memory computing marks a significant breakthrough in the field of computing technology. This innovative approach, focused on storing and processing data within the processor, opens up new prospects in energy efficiency and applications in the field of artificial intelligence.

Molybdenum disulfide, with its three atoms thick, acts as the operating channel of transistors, much like graphene in the semiconductor world. Researchers produce entire wafers of this material, used to create a processor chip, with an area of 1 cm2. This production technology can be implemented in existing silicon processing plants.

Each MoS2 transistor in the processor is equipped with a floating gate control, which serves as data storage and transistor control. This allows the processor to perform calculations internally, without the need to transfer data to external devices. The developed prototype is designed to perform an important vector-matrix multiplication operation, widely used in the field of digital signal processing and artificial intelligence.

By creating a large-scale working prototype, the researchers demonstrate the promise of mass production of similar processors, promising revolutionary changes in computing technology.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Electronic helmet for truck drivers 14.04.2024

Road safety, especially for drivers of heavy construction equipment, is a top priority for engineers and scientists. In light of this, the German Fraunhofer Institute for Structural Strength and System Reliability has introduced a new product - an electronic helmet, which is designed to protect drivers from serious injury when driving construction vehicles. A new electronic helmet developed by a team of engineers from the Fraunhofer Institute opens up new perspectives for the safety of truck and construction equipment drivers. The device is capable of monitoring the level of shaking in the car cabin and warning the driver of possible danger. The basis of the helmet's operation is a built-in piezoelectric sensor, which generates electricity during physical deformation. This mechanism allows the device to respond to intense vibrations typical of construction equipment. When the level of deformation exceeds safe values, an alarm system is activated on the helmet, ... >>

Antivitamins instead of antibiotics 13.04.2024

The problem of bacterial resistance to antibiotics is becoming increasingly serious, posing a threat to the effective treatment of infections. In light of this, researchers are looking for new ways to combat superbugs. One of the promising directions is the use of antivitamins that can have an antibacterial effect. Antivitamins, although known as the opposite of vitamins, have proven to be a promising tool in the fight against bacterial antibiotic resistance. A study conducted by scientists from the University of Göttingen in Germany confirmed their potential in creating new drugs to combat dangerous infections. With the rise of antibiotic-resistant superbugs, there is a need to find alternative treatments. Antivitamins are molecules similar to vitamins, but capable of inhibiting bacterial activity without harm to the human body. At the moment, science knows only three antivitamins: rose ... >>

Temperature sensor TMP107 22.11.2016

The new TMP107 temperature sensor supports up to 32 devices in series. A chain of TMP107 sensors is connected to the microcontroller via one single-wire UART interface.

Each sensor has a unique 5-bit address stored in electrically erasable programmable memory (EEPROM). The address is assigned during the auto assignment operation and is based on the position of each sensor in the chain. The transmission distance of the UART bus can be up to 300 meters. Data is transmitted between sensors using the proprietary SMAART Wire protocol.

The TMP107 provides maximum flexibility in use, allowing you to choose between low power consumption (e.g. when running on batteries) and high refresh rates for real-time applications.

The warning function of the TMP107 is implemented with two registers for storing programmable values for low and high temperatures. After each measurement, the temperature is compared with the values from these registers. When the specified range is exceeded, the sensor sends a corresponding signal, which can be processed by the microcontroller or displayed on the alarm warning LED.

The TMP107 is capable of reading temperature with a resolution of 0,015625°C and an accuracy of +-0,4°C in the range from -20°C to +70°C. This sensor is ideal for replacing NTC and PTC thermistors in applications requiring high measurement accuracy, such as industrial, medical, environmental, and grain storage temperature control systems.

The TMP107 is housed in a SOIC-8 package and is designed for use in a temperature range of -55°C to +125°C.
