Neuromorphic Revolution to Start in 2024

Deep learning is “not actually learning,” said Mike Davies, head of Intel’s neuromorphic computing unit at this year’s International Solid State Circuits Conference. His words revived the neuromorphic debate through the AI community at a time when data bandwidth constraints and computational requirements escalate.  2024 is expected to be the start of the neuromorphic revolution,…

CO2 Sensors Help Smart Devices Clear the Air

A primary objective of innovation is improving the human condition. For developers of smart-building applications and related tools, improving the quality of life includes ensuring the quality of the air we breathe. Most people spend up to 90% of their time indoors, and the indoor concentrations of many pollutants can often be two to five…

High-Performance Magnetic Sensors Speed EV Charging

Environmental policies are leading us toward zero-emission targets in most major cities of the world by 2050. Achieving zero-emission mobility is critical to reducing the polluting airborne particulate matter present in many urban environments and containing the associated health problems. Toward that end, entrepreneurial and tech strategies have emerged to support a rapid-recharge infrastructure for…

Transducer Options for Safe, Precise Current Sensing

Current measurement is an integral part of power electronics. Power supply designers, battery management systems, and motorized drives often need to measure current accurately. Current transducers (not to be confused with current transformers) can measure both DC and AC. Current transducers are most often based on closed-loop Hall-effect or closed-loop flux-gate technology. Typically, power requirements…

Motor Speed Control Using Hall-Effect Sensors

A Hall-effect sensor varies its output voltage in response to a magnetic field. Hall-effect devices are used as proximity sensors and for positioning, speed, and current detection. They are widely used in motor control systems. A Hall-effect sensor is a long-lasting solution because there are no mechanical parts to wear down over time. The integrated…

Focus on Sensor and Measuring Technology for Process Automation

SENSOR+TEST, the leading forum for sensors, measuring, and testing technologies, will take place June 25–27 in Nuremberg, Germany. About 540 exhibitors are presenting the entire spectrum of measuring and testing system expertise, from sensors to computers. With its special topic, “Sensor and Measuring Technology for Process Automation,” SENSOR+TEST 2019 addresses the increased demands in one…

High-Performance Design for Ultrasound Sensors

Ultrasound waves are sound waves with frequencies above 20 kHz, which is the average upper frequency limit detectable by the human ear. Ultrasound waves are subject to reflection, refraction, and diffraction phenomena and can be characterized by their frequency, wavelength, and propagation speed, as well as the attenuation that occurs as the wave passes through…
