Cambridge’s Flusso launches world’s smallest flow sensor

Flusso Cambridge Andrea De Luca and Florin Udrea

Flusso, a semiconductor business spun-out of the University of Cambridge, has launched what it dubs the world’s smallest flow sensor as part of a complete flow sensing solution for use in high-volume consumer and industrial markets.

The new FLS110 flow sensor, with a footprint of just 3.5 x 3.5 mm, is small enough to fit into virtually any product and is based on pioneering sensor research, first developed within the Electrical Engineering Department at the university. 

The FLS110 is being launched with a comprehensive package of online and dedicated design and engineering support, making it as easy as possible for product manufacturers to incorporate reliable flow sensing into their products for the first time.

Target applications for the technology include active filter monitoring in vacuum cleaners, air-conditioning units and other consumer appliances, where the sensor could be used for example to indicate to users when a filter is damaged or blocked.

The FLS110 could also lead to new generations of home healthcare products, such as smart inhalers and fitness monitoring equipment, as it’s described as the only cost-effective technology capable of providing detailed monitoring and feedback, while being small enough to easily fit into handheld devices.

Flow measurement is often seen as being a difficult and time-consuming function to implement, requiring specialist engineering expertise and knowhow. And where product manufacturers have limited scope to customise existing off-the-shelf solutions for their specific application.

Flusso has taken a completely different approach to the flow sensing market.  Its FLS110 flow sensor has been designed for maximum ease of use, to be fully customisable, and to give customers the flexibility to decide the ideal balance of performance versus cost within their system.

It also covers a wide flow measurement range – from as low as 0.001 up to over 500 standard litres per minute – so the same component can be used across multiple applications.

Flusso is already supplying samples of its FLS110 flow sensor to customers as part of a product evaluation kit. The company plans to take its new flow sensor into volume production in the first half of 2021.

Flusso was co-founded by Professor Florin Udrea (co-founder of CamSemi, Cambridge CMOS Sensors, Cambridge Microelectronics, and Cambridge GaN Devices), Professor Julian Gardner (co-founder of Cambridge CMOS Sensors and Sorex), Dr John Coull and Dr Andrea De Luca – all sensor experts with extensive experience in the semiconductor industry.

The company completed its Series A round earlier this year to raise $5.7 million led by existing investor Parkwalk Advisors. In September, Dr Andrea De Luca, CEO at Flusso, was awarded a Young Engineer of the Year award by The Royal Academy of Engineering for his outstanding work in new sensor development.
