In This Issue    • Wafer-Scale Sensors    • College Students Eventually Learn Wafer-Scale Sensors You might have heard a lot about NVE's new, ultraminiature wafer-level chip-scale package sensors. But sometimes, more really is MORE, so this April 1, we're introducing our new wafer-scale package sensors. A Big Difference Available in state-of-the-art 450 mm and 300 mm wafers, as well as legacy 200 mm formats, these new sensors are a fully monolithic solution designed to push the sensitivity of TMR sensors to the final frontier—literally. Each 25-wafer lot ships in a high-protection case with rolling wheels and a recommended two-person lift procedure. Go Large Large packages means large flux concentrators and large TMR junctions, enabling a solution to effectively upend the market for SQUID and SERF magnetometers. Key features include:   • Large packages from 200 to 450 mm   • Large sensitivity from 100 mV/V/µT to 100 kV/V/µT   • Large temperature range from -40 to +125°C   • Large prices, because wafers don't come cheap (although neither do SQUIDs or SERFs)   Sounds Like April Fools' but Isn't A research group used NVE high-sensitivity sensor evaluation boards in a study that roughly concluded that college students will eventually learn something if you keep repeating it. The authors note that ethical approval was obtained from the Swedish Ethical Review Authority, presumably since you're allowed to do just about anything to undergraduates. The results were published in the journal Science of Learning. Excerpts: "Our findings show, for the first time in humans using this protocol, that learning improves substantially on days 2 and 3." and most importantly: "Participants were equipped with custom-made glasses that had a nozzle for aiming and delivering the air puff, and a GMR chip (AAH002-02E, NVE Corporation) attached to the frame of the glasses."
