This Printable Sensor Can Successfully Detect Spoiled Food

Nowadays, even safe-to-eat food can be thrown away. There are a lot of reasons for it, for example, it is allegedly expired or under poor storage conditions. Researchers have recently found a way to solve this problem based on the connection between sensor and phone.

A team of researchers at the Imperial College London has successfully developed a type of food sensor. Now, we do not need to care about the expiry date of food anymore. The initiative will help us accurately detect the quality and safety of food. Therefore, we can continue to use food and avoid wasting food.

The name of the new sensor is the PEGS (Paper-based Electrical Gas Sensor). It is very thin in size and can be printed on food packaging. In fact, it includes Carbone electrodes printed on paper. This device is made of friendly and non-toxic materials. Therefore, they are safe with food and human health.

The new sensor can detect gases like ammonia in decayed meat and fish. Also, the printed tags come with NFC tags, which allows customers to scan directly via smartphones. The quality of the product will be analyzed and sent to your phone. Therefore, the user can know the quality and expiry date of the food.

With this sensor, the expiry dates on the food package will be unnecessary at all. More importantly, users spend around Rs 1.39 printing a tag.
