Kannada actor Dileep Raj died after a suspected cardiac arrest, with reports claiming smartwatch readings may have delayed him from seeking urgent medical help. The case is reigniting warnings from experts that wearables can’t replace professional diagnosis, and concerning symptoms should be treated immediately rather than relying on device reassurance.
South Korean researchers say they’ve built a wearable neckband that converts silent mouth movements into intelligible speech using the user’s own voice. Because it doesn’t rely on audible input, it could help communication in extremely noisy settings and support medical use cases. The technology is early-stage, but the approach could redefine how we “speak” without speaking.

Google has launched the Fitbit Air, a lightweight screenless fitness tracker designed to work with both Android and iPhone. The device pairs with AI health coaching and prioritizes sleep, recovery and heart-rate monitoring, packaged with smart fitness tools. Google is signaling a major push toward AI-powered wearable health features, backed by a week-long battery promise.
Google has unveiled a screenless Fitbit Air that targets always-on health tracking. The wearable promises 24/7 heart rate, heart rhythm monitoring with Afib alerts, SpO2 readings, resting heart rate, heart rate variability, and detailed sleep stages and duration, positioning it as a Whoop-like alternative focused on continuous insights rather than display-based interaction.
Japanese scientists say they’ve built a wearable that generates electricity from human sweat using special enzyme ink. The breakthrough could remove batteries and charging cables entirely, while still powering low-energy sensors. Once operating, the device can wirelessly transmit data—an approach that may reshape the design of future health monitoring gadgets by making them more sustainable and convenient.
BCI startup Neurable says its “non-invasive” neural data collection could move from research to real consumer wearables. The company is exploring a licensing model for its mind-reading tech, aiming to enable new hands-free experiences and applications outside the lab—assuming the challenges of accuracy, comfort, and privacy can be solved at scale.
