Smart toilet gives nutritional advice

30 August 2019

Visitors to Lowlands Festival 2019 in the Netherlands have been using smart toilets in an on-site restaurant, which measure a number of health aspects. Based on the collected data, visitors receive a suggestion for a dish that fits a balanced nutritional requirement.

The smart toilets, based in Rabobank's restaurant Brasserie 2050, measure urine, heart rate and blood pressure changes which provides insight into dietary habits.

If the toilet measures a high heart rate, it might suggest that a dish with more fibre and moisture can help. The ion sensor measures the conductivity of your urine and indicates that you may need more fluid. After visiting the smart toilet, visitors receive nutritional advice with food and drinks they can buy at Brasserie 2050. 

The aim of the information is also to question whether you actually eat what you need. Around 10 billion people will live in the world by 2050. To keep pace with world population growth, food production needs to increase by around 60% and its ecological impact reduced by 50%, according to financial services provider Rabobank.

"We are focused on innovations that contribute to solving the global food problem, on all fronts, large and small," Rabobank said. "Thanks to personalised food suggestions that the Smart Toilets provide, we can focus in the future on what food we actually need and perhaps, as an extension of the current project, reduce the negative impact on the environment through food wastage."

The Smart Toilets are developed by imec Netherlands, a subsidiary of imec, the Belgian research and innovation hub in the field of nanoelectronics and digital technology. The Smart Toilet was created in a collaboration between Rabobank, The Food Line-up, MOJO and imec Nederland.
