A student-founded startup creating paper sensors to monitor breathing rates of hospital patients has won the White City Innovators' Programme.

SpiraSense, founded by Imperial student George Winfield, is developing the low-cost sensors to speed up the diagnosis and treatment of sepsis in hospital patients. 

The device learns from every breath a patient takes. It would allow doctors to see trends that might not be immediately apparent George Winfield Founder

Sepsis is a life-threatening condition responsible for 44,000 deaths every year in the UK. It arises when the body overwhelmingly over-reacts in trying to control an infection, injuring its own healthy organs and tissue in the process, and is a particular risk for people already in hospital because of another serious illness.

If it is caught early and treated quickly, most people make a full recovery. But without rapid treatment, sepsis can quickly lead to multiple organ failure and death in just a few hours. 

Low-cost solution

One of the early symptoms of sepsis is rapid breathing. Currently, breathing rate is measured manually by doctors on observation rounds.

If adopted, an AI powered app could then alert doctors to possible patient deterioration in real time, allowing for faster diagnosis and treatment. 

George, who is undertaking an MRes in Medical Device Design & Entrepreneurship at Imperial, said: “The device learns from every breath a patient takes. It would allow doctors to see trends that might not be immediately apparent from manual observations, giving them more information to make an informed decision about patient care.” 

Their small paper sensors, which are about the size of a postage stamp, are designed to attach to any breathing mask or nasal cannula already used in hospitals, potentially offering a low cost solution. 

SpiraSense was awarded a £7,000 prize package, including a 12-month membership at the Imperial Incubator and £5,000 to support the business’s growth. 

George is currently engaged with securing further funding to develop his device ready for clinical testing. 

Boosting growth 

Delivered in partnership with NatWest, the Innovators’ Programme is the Imperial Incubator’s flagship pre-accelerator programme. It aims to support the development of technology focussed early-stage companies by providing funding, mentoring, access to Imperial’s innovation ecosystem, free space to work, and training in areas such as fundraising, team building, IP, marketing and pitch practice. 

The programme runs twice a year at the White City Incubator, and is aimed at Imperial alumni, current students, and tech businesses from the local area. 

George added: “It has been fantastic to work with such a diverse range of people and businesses on this programme. You really learn a lot from other perspectives and approaches. 

“The mentoring on the programme has been especially valuable. It’s great to be able to bounce ideas around with people who have such great experience and networks.” 

The programme culminated in a pitching event on the 24 May, where eight participating businesses pitched their ideas to a panel of judges. The panel included Dr Govind Pindoria

Local White City resident Sasha Pinnock was awarded third prize for SP Tracked Safety Jackets, a business that creates GPS trackable high-vis jackets. The jackets would allow parents and guardians of small children or carers of vulnerable adults to keep track of where their loved-ones are and monitor their safety 

Fourth prize went to ifPlus, founded by Imperial College Business School alumnus Tassilo Vogel, a decision-making tool and knowledge sharing platform that would allow users to search for advice for a variety of different situations.
