RethInk electronics with n-Ink

The project

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.

Interested in working with n-Ink?

Applications

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

Application

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

Application

Organic supercapacitors

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

Application

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.

OLED

Application

OLED

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.
