Internet of things (IoT) comprise electronic devices, such as batteries, displays, solar cells and sensors, and is revolutionizing our society by providing radically new means to aid us in our modern lifestyle. At their core, IoT technology is typically built up from the merger of silicon chips, providing computation, and a vast array of different dedicated flexible polymer devices, providing sensing and powering. Together such systems enable new functionalities and easy integration with for instance textiles, paper and large area carriers. However, low power operation and advanced functionality require devices that depend on a balanced transport of positive (holes) and negative (electrons) charges. For the silicon chip technology, such complementary electronics is the heart of today’s digital processors. While polymeric hole (p-type) conductors are being developed to industrial scales, equivalent electron (n-type) polymer conductors are missing. This limits the full potential of many IoT applications as optimal performances can only be achieved via complementarity. n-Ink addresses this challenge, by formulating and supplying n-type inks with unprecedented performance. Our patented n-Inks are highly conductive, easy to handle, stable and printable. For the first time, n-Ink is offering electron conductors that are on par with commercial p-type inks to bring a new paradigm of printed electronics to the market.
