Teradar reveals its first terahertz-band vision sensor for cars

Boston: Teradar, a company from Boston, has just revealed its first terahertz sensor named Summit at the CES 2026 event. This sensor is special because it works really well in any type of weather, filling important gaps left by older sensors like radar and lidar. The company believes it can help cars become partially or fully self-driving, which is exciting for the future of vehicles.

Teradar aims to begin shipping the Summit sensor by 2028 if it can secure contracts with car manufacturers. This sensor uses a part of the electromagnetic spectrum that isn’t fully utilized yet, sitting between microwaves and infrared. Unlike some sensors, it has no moving parts, giving it advantages of both radar and lidar.

The timing is crucial since many car makers are rethinking their sensor choices. A major lidar company, Luminar, just faced bankruptcy after losing contracts with big names like Volvo. This happened partly because cheaper options from China became more popular. On the other hand, Teradar is already collaborating with five major automakers from the U.S. and Europe.

They are also seeking diverse uses beyond cars. Their recent $150 million fundraising included investors like Lockheed Martin’s venture arm. Even though lidar is still in the game—like Rivian planning to use it in their new SUV—Teradar’s CEO, Matt Carey, is eager to get their sensor on as many vehicles as possible. He believes it can meet all required features for the future of driving.
