Apple redesigns the Watch’s heart sensors to take a reading every five seconds
Series 12 and Ultra 4 add a ring of photodiodes, larger green LEDs and bigger ECG electrodes. Apple bases its accuracy claim on its own 1,000-person study.

Sensors
Printed pressure arrays, biosensors, environmental sensing and the readout electronics that make them useful — the fastest-growing corner of printed electronics.
Battery-free printed NFC sensor tags find their first real volume in cold chain
The battery-free sensor tag has been a demo for years. Cold-chain compliance gave it a customer whose problem is per-package evidence — the one question a tag with no power source can answer.
Printed methane sensors edge toward the field as emissions rules tighten
Low-cost printed gas sensor arrays are targeting the leak-detection gap left by expensive optical methane monitors, just as emissions reporting rules tighten.
Printable pressure sensors find their volume market in soft robotics
After a decade of conference demos, printed pressure arrays are shipping in soft grippers, rehabilitation wearables and surgical training tools — applications where conformality beats the precision of silicon MEMS at a fraction of the cost.
