Laser measurement can calibrate a precision microphone as well as traditional techniques, according to the US National Institute of Standards and Technology (NIST). Such calibration is required in standards laboratories so that the microphones in sound-level meters and hearing aid testers, for example, can be set-up at the other end of the calibration chain. Traditional ...

Q2 foundry revenue grew 6.2% q-o-q to reach $24.407 billion, reports TrendForce. TSMC had revenue of $13.3 billion, a 3.1% q-o-q increase. TSMC’s relatively muted growth was mostly caused by a power outage that occurred in TSMC’s Fab14 P7, located in the Southern Taiwan Science Park, in April. The power outage subsequently caused some wafers ...

The triboelectic effect can be enhanced in wood so that it generates small amounts of electricity when stepped on. Two layers of wood are required, one spin-coated with PDMS (polydimethylsiloxane) – an electron acceptor on contact (‘tribo-negative’) – and the other with nanocrystals of ZIF-8 grown in one surface – ZIF-8 (zeolitic imidazolate framework-8) is ...

Analog Devices has introduced a step-down switching regulator that delivers up to 120mA from up to 42V, then shuts down to 2.5μA. Operating down to 3.2V (2.9V typ), the synchronous LT8604 will switch as fast at 2.2MHz and as slow as 200kHz – programmable by resistor. Efficiency can be over 90%. Topology is peak current mode, with ...
