Disruptive Technologies is the manufacturer of the world's smallest wireless sensors. These IoT sensors are tiny, robust, low cost and scalable with a long battery lifetime. VARTA supplies the primary lithium coin cell CR1216, which enables the small size of the sensor through special battery assembly and low weight. A custom connection to the battery is provided by VARTA to allow for a miniaturised sensor design. Due to a low internal resistance, a high pulse load can take place. The button cell has a runtime of up to 15 years and a low self-discharge for long storage and operating time. It withstands a wide temperature range and operates with UL certification.

“The high and repeatable quality of the button cells with customized pin tags was the main criterion for selecting VARTA as supplier”, says Oystein Moldsvor, VP of Engineering at Disruptive Technologies.

Wireless sensors belong to the field of the Internet of Things. They are designed to make our everyday lives easier and more convenient by connecting several components with each other, thus ensuring an intelligent exchange of data between the devices. Wireless sensors are used, for example, in smart buildings and facilities management, in the area of smart offices and workplaces, and smart manufacturing and warehousing.

VARTA develops battery solutions for the future that empower others to make their products even better – and that means smaller, more powerful and more independent.

Founded in 2013, Disruptive Technologies (DT) is the Norwegian developer of the world’s smallest wireless sensors and an award-winning innovator in the IoT market. The company’s tiny, efficient, powerful, and adaptable wireless sensors and solutions provide huge insights and are designed to reach an ever-greater number of operational components, making buildings intelligent and sustainable, in minutes.
