Skin cancer detecting device picks up £30,000 Dyson prize

0

An affordable and effective device for detecting skin cancer has picked up an award of £30,000 ($40,000) from Britain’s best-known inventor.

This year’s James Dyson prize for engineering was given to a group of four Canadian graduates, for their sKan system.

The gadget picks up on subtle changes in the skin’s ability to retain heat, which can indicate the presences of cancerous tissue.

The device costs £760 ($1,000), compared with the £20,000 ($26,000) for high-resolution thermal imaging cameras.

The device was chosen as international winner by inventor James Dyson, who made his name with his range of cyclonic separation vacuum cleaners.

About the project, Sir James said: ‘By using widely available and inexpensive components, the sKan allows for melanoma skin cancer detection to be readily accessible to the many.

‘It’s a very clever device with the potential to save lives around the world. 

‘This is why I have selected it at this year’s international winner.’  

The winning team says it plans to use the prize money to reiterate and refine their design, to ensure it passes the US Food and Drug Administration’s standards.

A spokesman for the team added: ‘We are truly humbled and excited to be given this remarkable opportunity.’ 

Research shows that cancerous cells have a higher metabolic rate than normal tissue cells.

The gadget picks up on subtle changes in the skin's ability to retain heat, which can indicate the presences of cancerous tissue. When an area of interest on the skin is rapidly cooled, cancerous tissue will regain heat at a faster rate than non-cancerous tissue

The sKan uses accurate and inexpensive temperature sensors to pinpoint areas of tissue that gain heat quicker than the surrounding area of skin. The results of this are displayed as a heat map and temperature difference time plot on a regular computer

A medical professional can use the findings produced by the sKan to indicate whether the patient needs to be referred for further investigation or not.

Annually, skin cancer accounts for one in every three cancer diagnoses.

The estimated five-year survival rate for patients whose melanoma is detected early is approximately 98 per cent.

Current melanoma detection methods either rely on a visual inspection, or need a specialist’s opinion which is time consuming and costly.

With high numbers of patients needing a rapid diagnosis to begin treatment, health services are at maximum capacity. 

The runners up of this year’s award were Atropos and Twistlight.

Atropos is a six-axis 3D printing robotic arm that uses continuous fibre composites material, to produce high-performance objects. 

The international James Dyson Award runners up are Atropos and Twistlight. Designed by Tina Zimmer, it uses LED lights to make veins appear highly contrasted within their surrounding dermal tissue

The light can be used to easily insert needles and catheters into a patient’s skin. Despite being the most common medical procedure, 33 per cent of first vein puncture attempts fail
