n-ink - Introduction
Breaking the Wall of Inefficient Organic Electronics n-Ink
Easy, stable, printable and patented n-Inks
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.

What we offer
Made to order
1) Materials with unique electrical properties
2) Easy-to-handle ink formulations
n-Ink provides several dedicated n-type ink formulations which are compatible with existing solution-deposition processes for Printed Electronics, Internet of Things and Bioelectronics. The strong scientific background of the n-Ink team allows for inks that are tailored to the needs of the customer. By leveraging our long-term collaboration with the Printed Electronics Arena, we ensure the highest material quality and scalable production processes.
n-Ink enables the development of highly performing printed electronic devices where efficient p-type (hole-transporting) and n-type (electron-transporting) materials are required.
Organic solar cells
Organic solar cells harvest light to produce electricity and require both p-type and n-type transport layers to extract the photogenerated current. Most n-type transport layers such as ZnO cause instability and thus, reduced device performance and lifetime. The unique electrical performance of n-Ink, featuring high and stable n-type conductivity, facilitates process integration and boosts performance and lifetimes.
Organic supercapacitors combine both p-type and n-type conducting electrodes to store electrical energy at fast charge/discharge rates. n-Ink provides materials featuring high conductivity and stability, which yields high capacitance per unit volume as well as high energy density.
Organic electrochemical transistors
Organic electrochemical transistors are an emerging technology platform with unique properties for IoT sensors, printed electronic circuits and bioelectronic applications. With an n-type ink at hand novel application and scientific opportunities arise, such as low-power circuitries and biosensors.
OLEDs emit light in displays and require both p-type and n-type transport layers to enable the injection of charges. The unique electrical performance of n-Ink, combined with its over-printability and stability, enables facile process integration whilst ensuring optimal device performance.
The experienced team
With more than 20 years of experience in material science, scientists at the Laboratory of Organic Electronics, Linköping University in Sweden, founded n-Ink in 2020 with the mission to rethINK printed electronics.
Simone Fabiano is CSO at n-Ink and a senior lecturer at the Department of Science and Technology (ITN) of Linköping University, where he leads the Organic Nanoelectronic group (ONE) as principal investigator. His research is at the cutting edge in the field of organic and printed electronics and his extensive knowledge and network allows his group to stay at the forefront of academic research, while keeping a strong outlook towards high-tech industries.
