FeelWrite self-recovery soft film technology

As handwriting lovers, we know that the experience of handwriting is more than just the act of writing by hand. There is also the feel of the paper and pen, the damping sensation that comes from the surface of the paper as the thought directs the movement of the pen, the variation in the thickness of the ink lines, the ornamental loops on capitals, and the precious humanity that automation doesn't have. We believe that the digital writing experience should be far more than the pale version that relies on the hard screen and the pen nib rubbing against each other.

In today's world, simulating the writing feel of a pencil on paper is relatively the easiest and most common. The method is to create the feel, even the sound, of a pencil by rubbing the nib against a hard screen. This is good for sketchers, but the nibs get dirty and deformed easily due to friction, which affects the handwriting experience, and requires frequent spending on new nibs to replace them.

Handwriting experience is compromised unless replaced with a new nib

We chose the harder path — simulating the writing feel of a gel pen/ballpoint pen on paper instead of a pencil, because for most people who write, these pens are better.

In fact, the modern paper-making process is based on essentially the same principles as Cai Lun, the inventor of paper-making more than 2,000 years ago, using water and natural fibers as raw materials to make paper by joining the fibers.

Engineers mix fibers extracted from trees and other raw materials with hot water to make pulp, and the fibers in the pulp are interwoven to form a film of paper through a paper machine, which is then dried and polished to give a smooth surface. When you writing on the paper, the paper fibers spread and recover as the nib is squeezed and relaxed. The FeelWrite film on the surface of the Supernote screen magically simulates the movement of the paper fibers.

When the hard ceramic nib is pressed down on the soft film, creating the "dent" on the surface that disappears following the movement of the pen nib. Under our 200 g pressure test, the film was undamaged when the pen was used to write continuously for a distance of 10 km, and you don't have to worry about the nib wearing out, it' s replacement-free, and always keeps an exquisite writing experience.

Why can FeelWrite soft film be self-recovering? This is due to the special materials and multi-layer structure. Working with a Japanese chemical company, we combined materials from industry, building materials, and OA equipment components to design the multi-layer structured soft film that is highly flexible and tough, and the multiple layers adjust the concavity of the film so that it does not become too concave and writing feels heavy.

In addition, the FeelWrite soft film also protects the screen of your device. Although developing and using the new technology significantly increased the cost, we persisted because we believe it means a lot, handwriting is not gone, it becomes digital.
