Paper-Based Electronics

Paper-Based Electronics aims for using cellulose fibres or organic-based substrates rather than mineral-based, oil-based or synthesis plastics to conceive and develop electronic parts and products.

Results are equivalent, appart from durability, as pure organic materials are quickly biodegradable while plastics are not.
Refined organic-based materials are made of locally renewable resources and they can be recycled if not buired or burnt with considerably less impact than non-biodegradable or non bio-compatible materials.
Their quality can be improved and controlled with a small amount of various chemical additives so as to increase

A thin external recyclable plastic cover is then only necessary to conceive a more durable and well protected product while the whole remains separable and recyclable in the recycling bin.

Building Custom Force Sensors

admin0106 Wed 24/03/2021 - 23:41

Force Sensing Resistors are among the oldest printed electronic components )invented in the 1980's by Franklin Eventoff) and for sure the mostly used force sensing concept as it fulfills our keyboards and many other touch key devices.

They can be found at standard shape and sizes from industrial manufacturers (Sensitronics, Interlink, Tekscan) or they can be house-made using resistive plastics or textiles and metal or metalised electrodes but here we like to build them from a combination of paper with metal-free electrodes and a highly sustainable finished product.

Check out these fabrications guides and other related resources to build any force sensor of any size and shape with a full control over the sensor response, its conditionning and its recyclability,

Description

As part of technical raw material developed and experienced since 2006 for electronic application, the conductive paper 1K has especially been designed as electrode layers for the custom fabrication of touch sensors and especially force sensing resistors.

It can also be used for its piezoresistive behavior under compression but the conductive paper 100K is more interesting for such applications.

This paper was also used for the design of anti-static or shielding materials, heat power transfer, temperature and humidity sensing or else as an electrode or functional layer in various components such as power sources.

Technical Details

This paper ca be disposed as standard sheets (A5, A4 or 1 Foot Square) or else as bigger sheets on request. The PLK-1K paper was intensively studied and we can provide the following specifications for our current stock:

Recycling

This product was made in Europe mostly from wood and cotton fibers. It also contains less than 25% conductive Carbon Pigments and a few percent chemical additives.

It can (ands should) be disposed in recycling beans. Simply leave it free from other bonded materials such as metal connectors or plastic cover.

It was also optimized to have a minimal impact when buried, burnt or lost in the wild: it is biodegradable over time and burns much more easily than synthesis polymers.

Produce Sustainable Goods

admin0106 Wed 31/03/2021 - 13:31

"How ca we keep counting on essentials and profitable goods and products while sufficiently lowering our impact upon the eco-system to reach a sustainable way of life?"

This could be the big question for this century as instead of taking place the year after, the overshoot day has kept coming sooner and we would now need 4 planets if every human beings on earth had the standard leaving of the French people.

Sustainable Goods have zero carbon, zero waste and they do not impact more the planet over time than what the planet and the eco-system can handle and renew. Let's just say these are rare artefacts today!

These pages provide keys to optimise the resources we use and the way we used them though a full consideration of the systemic parameters that can influence a product life-cycle.

Scalable Load Cells

admin0106 Sun 28/03/2021 - 20:55

Based on thin Force Sensors technologies used to detect small force variations, the Load Cells are covered by a rigid surface to spread the force applied and used for a wider range of gesture such as pushing or stepping over it with the whole body.

Various sizes and shapes can be designed depending on the load variations to be detected.

The PapierLogik network gathers a variety of research Labs, fablabs and industrial partners in the fields of papermaking, printing, converting, electronics and computer science as well as alternate fields such as recycling.

We aim for developping sustainable electronics, which implies to carefully select our resources but also to optimise the ways we will exploit these and minimise our energy and water consumptions, as well as our ecological impact.

Papier Logik development kits have been used world-wide since 2007 by students, researchers, designers or artists for the production of custom electronic interfaces. They gather essential resources for the production of efficient components such as touch sensors or complete control surfaces.

These resources also found a strong interest for teachers in Arts, Sciences and Technologies who helped developing specific kits for educational purpose.
