Flexible hybrid electronics is one of the key technology that enables to combine the benefits of printed electronics with that of modern silicon electronics. In this work, a prototype of hybrid flexible smart temperature tag is proposed for environmental temperature monitoring. The tag is designed with sensing and processing capabilities as well as NFC (near field communication) compatibility. It can be used for potential temperature-sensitive products management and smart packaging; thus not only the end-users/consumers who concern about the quality issues of the products can be benefit, but also the manufactures/distributors can make use of this tag into the temperature-controlled supply chain management and tracking system for various temperature-sensitive products and applications, such as bio-medical & pharmaceutical products, high-class foods and beverages, etc.
