KILL THOSE GERMS...... before they kill you!

80% of infection diseases are spread by touch, research from the British Toilet Association shows that 30% of the general public do not wash their hands after using the toilet and 88% do not wash their hands for long enough to kill germs.

This is a hygiene sensor, it detects if any bacteria are still present on the hands after washing. The ultra violet rays show the parts of the hand that still contain the bacteria so the user can thoroughly wash their hands again to remove all chances of carrying harmful bacteria.  

What are the benefits of your concept for the individual and the employer?

By integrating this design into all toilets in a workplace, the spread of bacteria causing infectious diseases could be reduced. Therefore less employees will take time off from work and less stress will be caused for the employer to find cover for the shift or loosing out on the business if a replacement is not found.

What might the impact of your concept be and how might it be measured?

The concept could be used in different environments, such as schools, university or even the home. By regularly checking if bacteria is present will reduce the amount of disease that is spread and potentially save lives, as harmful bacteria can kill. To measure how often the device is being used a sensor can monitor the amount of times the entrance to the toilet is being opened, and this could be compared to the actual hygiene sensor to see how many people have actually used the sensor.

How might you design a small experiment around your concept that would mobilise action?

An handheld ultra violet ray device could be placed in toilets to allow users to check if they have cleaned their hands properly. And then another device can monitor how many times the UV device was picked up to use. If the device was frequently used, then that shows that users would like a device like this in their toilets.
