Vayyar’s 3D ultrawide band (UWB) radio sensors provide the ability to look into and beyond solid objects and sense material composition and have multiple potential applications from health, smart-home through to autonomous driving and defence.

The latest round was led by Walden Riverwood and ITI with additional funding from Claltech and follow-on investment from Battery Ventures, Bessemer Ventures, Israel Cleantech Ventures and Amiti, bringing total capital raised to date to $79 million. Vayyar said it would use the money to grow its global team, broaden its sensing product offering and expand into new industries.

The company was originally started with the goal of using radio wave imaging technology to see into human tissue to detect early stage breast cancer.

Vayyar’s sensor is an IC containing dozens of transceivers that transmit on wide and flexible frequency bands. It is able to receive, analyze, and create high-resolution 3D images.

Vayyar’s sensors create a 3D image in realtime, without the use of a camera. These sensors can see through solid objects, map large areas and can be used in privacy-sensitive locations where optics cannot. Providing a look beyond human vision, Vayyar’s sensors have expanded across industry sectors, including smart home, automotive, retail, robotics, medical, construction, agriculture and more.

Lip-Bu Tan, chairman of Walden International and managing director of WRV, said: “Vayyar’s technology has disruptive potential across a myriad of different industries. Vayyar is growing fast, and we look forward to helping Vayyar impact the automotive and smart home industries in a similar way.”
