Over the past few weeks, we explored the deep infrastructure that powers AI: memory, photonics, chiplets, quantum, power, and cooling. This week, we move from the data center to the things people actually use.

A new class of AI wearables and compact devices is emerging. They are smaller, faster, more personal, and far more capable than the gadgets of just a few years ago. What makes them possible is not bigger models, but better silicon.

To run intelligence on the wrist, in an earbud, or inside glasses, chips must be efficient, quiet, cool, and capable of handling real workloads without draining a battery in minutes. That constraint has produced some of the most interesting hardware innovation in the consumer space today.

Syntiant

Always On Intelligence for Tiny Devices

Syntiant focuses on the lowest power tier of AI wearables. Its Neural Decision Processors are designed for always on listening and sensing in earbuds, glasses, fitness bands, and other battery powered products.

Recent updates:

  • Syntiant’s chips already ship in millions of devices for tasks like wake word detection and environmental sensing.

  • New digital microphones with embedded neural processors enable AI based noise cancellation inside earbuds and headsets.

  • Ultra low power presence detection allows devices to wake higher power systems only when needed.

Syntiant gives wearables the ability to be attentive without draining the battery.
