CMOS terahertz startup gets EC equity backing
TiHive in Grenoble has raised €8.6m ($10m) for its CMOS terahertz chip, including equity funding from an fund run by the European Commission
do the processing. We have built camera systems, to a CMOS chip with optics, then AI embedded on the camera,” he said. Each camera has 1000 pixels with 12bit resolution operating at 1000 frame/s.

“This can democratise terahertz sensing in a similar fashion to smartphones with cameras that can be integrated almost anywhere and can be produced at large scale. In a couple of years we want to provide tens of thousands of cameras,” he said.

“We want to develop that one standard die camera with a standard API to develop applications of your choice. We will unlock one application that requires many cameras as the beachhead market. When that camera is standardised it will be a matter of software,” he said. “But we are not yet there. Today everything is on a single chip with off the shelf processing. When we detect THz, its a complex mechanism, and we need to process this before it goes to the processor at high speed. WeE have developed that chip with the camera and embedded systems.

The first application is in hygiene and personal care, measuring the dosage of absorbent polymer that goes into nappies/diapers. This is half the cost of the product, and overdosing costs the industry one to two billion euros a year on factory lines that produce 1200 items a minute. Hundreds of TiHive cameras can be added to existing lines to monitor the amount of polymer delivered.

“TiHive’s plug and play solution consists of integrated circuit-based technology and artificial intelligence algorithms. It includes a transmitter and receiver, which, when positioned either side of an object, reveal physical characteristics or quality indicators that have previously been impossible to measure,” said Clement Jany, CTO of TiHive.

“That will reduce costs by €2bn and reduce waste of the non-bio-degradable materials,” said Sherry. “With the same camera we are detecting other factors such as contaminants.”
