Holo Electronauts!!! Our world is a symphony of light, and electro-optical (EO) sensors are the maestros, conducting this invisible orchestra. These remarkable devices translate light into electrical signals, unlocking a treasure trove of information about our surroundings. 𝐁𝐮𝐭 𝐰𝐡𝐚𝐭 𝐞𝐱𝐚𝐜𝐭𝐥𝐲 𝐚𝐫𝐞 𝐄𝐎 𝐬𝐞𝐧𝐬𝐨𝐫𝐬? Imagine a tiny detective – that's essentially what an EO sensor is. Embedded within various devices, these sensors capture light waves, be it visible light, infrared, or ultraviolet. By analyzing these waves, they unveil hidden details about objects, materials, and even their motion. The world of EO sensors is constantly evolving. From miniaturized versions integrated into smartphones to powerful LIDAR (Light Detection and Ranging) systems, the possibilities are endless. These advancements promise even more precise imaging, faster data acquisition, and deeper insights into the world around us. ----------------------------------------------------------- Share with your friends if you're an electronic enthusiast!!

In a new Nature study, Columbia Engineering researchers have built a photonic chip that can produce high-quality, ultra-low-noise microwave signals using only a single laser. The compact device — a chip so small, it could fit on a sharp pencil point — results in the lowest microwave noise ever observed in an integrated photonics platform. The achievement provides a promising pathway towards small-footprint ultra-low-noise microwave generation for applications such as high-speed communication, atomic clocks, and autonomous vehicles. https://lnkd.in/dE8GsUDf

MEMS technology has been around for decades, but right now we see a big change happening: the increasing commercialization of piezoelectric MEMS devices. Why?   Many of the microelectromechanical systems (#MEMS) we use daily– like airbag accelerometers, microphones and gyroscopes in our smartphones– have typically been based around capacitance. Capacitance arises between charged surfaces that are separated by a small gap. A physical phenomenon, such as a sharp acceleration, changes the separation between two the surfaces, causing a change in capacitance, which can be measured as an electrical signal.   Today, more and more MEMS devices are being built into applications in homes, vehicles, supply chains, healthcare networks, and beyond. There is also growing requirement for smaller devices that can still provide faster response and larger range of motion (such as LiDAR, AR/VR headsets, micro-speakers, and pressure/temperature/gas sensors).   But with the continued demand for reliability, manufacturability, and performance, capacitive MEMS technology is hitting its limits.   The good news is: piezoelectric MEMS offers substantial performance and manufacturing gains over traditional capacitive MEMS. Jérôme Mouly of Yole Group confirms that piezo MEMS is a growing trend, citing applications like earbud micro-speakers and piezoelectric machined ultrasonic transducers (PMUTs) for ultrasound applications.   In a piezoelectric material, mechanical stress generates an electrical charge. This property can be harnessed to detect incoming pressure waves in a microphone, for example. Conversely, applying voltage to a piezoelectric material can produce movements, as in micro-speakers and earbuds, for example.   With advances in microfabrication processes, thin films of piezoelectric material have been integrated into MEMS manufacturing. Piezoelectric-based MEMS provide a more direct and linear actuation and detection mechanism compared to capacitive architectures.   Overall, the rise of piezoelectric MEMS technology can be attributed to the three-fold convergence of 1. technological advancements, 2. growing demand for miniaturized devices with high performance, 3. the expansion of applications requiring precise control and sensing.   Follow us for more insights about piezo MEMS: https://lnkd.in/er-J_Wyt   Next topic: A brief history of piezoelectric MEMS   #MEMS #piezoMEMS #sensors #ultrasound #PZT #piezoelectric

Programmable matter refers to materials or substances that can change their physical properties, shape, or functionality based on external commands or inputs. These materials often consist of tiny components like microcontrollers, sensors, or actuators embedded within a matrix. By manipulating these components, programmable matter can reconfigure itself into various forms or structures, enabling applications such as shape-shifting robots, self-assembling furniture, or adaptive infrastructure. Research in programmable matter aims to create dynamic materials that can adapt to different tasks or environments autonomously. #TechTuesday #innovation #matrix #sensors #actuators #infrastructure #experiontechnologies Experion Technologies

Hola Technocrats!!! Have you ever wondered how your phone knows when its case is closed, or how a brushless motor in your drone spins so smoothly? The answer might surprise you: it's all thanks to a tiny sensor called the Hall effect sensor. 𝐖𝐡𝐚𝐭 𝐢𝐬 𝐢𝐭? The Hall effect sensor is a fascinating piece of technology that uses a principle called the Hall effect. When a magnetic field is applied to a conductor with current flowing through it, a voltage is created at right angles to both the current and the magnetic field. This voltage, known as the Hall voltage, is proportional to the strength of the magnetic field. So, the next time you interact with a device that uses magnets or senses position and movement, remember the silent hero behind the scenes: the Hall effect sensor, a testament to the ingenuity of human innovation. ----------------------------------------------------------- Share with your friends if you're an electronic enthusiast!!

🗞 Electronic News! 🗞 STMicroelectronics has recently unveiled a new single-zone Time-of-Flight sensor, the ST VL53L4ED, designed for industrial and harsh environments with an extended operating temperature range from -40°C to 105°C. The ST VL53L4ED ToF sensor is capable of proximity detection and ranging up to 1150mm even under high ambient light conditions. This makes it suitable for a wide range of applications including industrial tools, smart-factory equipment, robot guidance systems, outdoor lighting controls, and security systems. #electricalengineering #electronics #embedded #embeddedsystems #electrical #computerchips Follow us on LinkedIn to get daily news: HardwareBee - Electronic News and Vendor Directory

The market analyst predicts that RISC-V will enjoy the strongest growth in the automotive sector, although the industrial space will remain the largest application for the technology. Additionally, the rise of AI will be instrumental in the continued rise of RISC-V. RISC-V is license-free, allowing anyone to develop hardware using the architecture and even to customize the instruction set according to the needs of the design. This will provide a key advantage of processor architecture provider ARM Holdings plc. #electricalengineering #electronics #embedded #embeddedsystems #electrical #computerchips Follow us on LinkedIn to get daily news: HardwareBee - Electronic News and Vendor Directory

Smaller components and higher frequencies: New CD Laboratory 23.04.2024: The Christian Doppler Laboratory for Distributed Microwave- and Terahertz-Systems for Sensors and Data Links opens at Johannes Kepler Universität Linz. Many modern electronic systems in a wide range of areas - from smartphones to navigation satellites - use signals in the high-frequency range for communication: On the one hand, the use of particularly high frequencies also allows particularly small components and enables larger bandwidths (e.g. for better data connections). On the other hand, new services often have to switch to higher frequencies because lower frequencies are already in use, and the susceptibility to errors, which must be counteracted, increases as the frequency increases. Head of Laboratory Reinhard Feger and his team are therefore looking into this promising but also challenging area of signal processing and are researching ways of integrating these high frequencies into semiconductor circuits, for example.
