Existing short-range radio technology was not made to meet the high expectations of emerging wearables.

Enhanced by artificial intelligence (AI), wearable devices are evolving from accessories into always-on multimodal interfaces. They increasingly require ultra-low latency for natural, conversational AI, microsecond synchronization across multiple body-worn nodes, and all-day battery life in very small form factors.

Bluetooth/LE Audio and proprietary 2.4 GHz links struggle to guarantee deterministic latency and multi-node time alignment in congested spectrum, especially under continuous audio and sensor workloads. Wi-Fi offers throughput but is power-hungry and often too variable for bounded-latency personal-area audio/sensor streaming.

The SPARK Microsystems platform is architected to enable ultra-low-power, sub-millisecond wireless performance in edge-AI wearables such as smart glasses and wrist devices by synchronizing audio, sensor, and high-data-rate links. It combines hardware, firmware, compact antennas and a reference compute module in its next-generation ultra-wideband connectivity platform that accelerates always-on AI wearable development.

This project delivers a Canadian low-energy UWB SiP and deterministic PAN software stack purpose-built for synchronized audio/video and sensor streaming. It reduces integration risk by providing a drop-in connectivity subsystem design that OEMs can adopt quickly, with robust operation under interference and strict energy budgets.

C2MI’s Bromont, Quebec, facility will provide advanced microelectronics assembly, packaging, inspection, and reliability testing, enabling rapid iteration and validation of the company’s LE-UWB SiP prototypes.

Bittele Electronics in Toronto will provide its quick-turn local PCB manufacturing, assembly, and design for manufacturing expertise to help produce prototypes. SPARK will also leverage the expertise of Motsai in Brossard, Quebec, which offers hardware design, embedded firmware development, and sensor integration.
