Teradar Summit Terahertz Sensor at CES 2026: A New Contender to Replace Lidar and Radar
Teradar unveils its Summit terahertz sensor at CES 2026, aiming to replace lidar and radar in autonomous vehicles with its high-resolution, all-weather performance.
The autonomous vehicle sensor market just got a serious wake-up call. Just two months after emerging from stealth with a $150 million Series B, Boston-based Teradar is showcasing its first flagship terahertz sensor at CES 2026. The company claims its new hardware fills a "critical gap" that legacy lidar and radar sensors have failed to address for years.
Inside the Teradar Summit Terahertz Sensor Technology
The Summit sensor operates on the relatively untapped terahertz band—sitting between microwaves and infrared. It's a solid-state device, meaning it has no moving parts, which promises higher reliability and lower costs than traditional lidar. Teradar says the sensor provides high-resolution data regardless of weather conditions, a major hurdle for current autonomous systems. If contracts with automakers are secured, the company expects to begin shipping units by 2028.
Market Turmoil: Lidar's Loss is Teradar's Gain
Teradar’s entry arrives as the lidar industry faces an existential crisis. Industry leader Luminar filed for bankruptcy in December 2025 after high-profile deals with Volvo and Mercedes-Benz collapsed. Meanwhile, Chinese competitors like Hesai have flooded the market, producing over 1 million units in 2025 alone. By positioning the Summit as a more robust and affordable alternative, Teradar is aiming for the sweet spot that established players missed.
