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.

Paper-Based Electronics

admin0106 Tue 25/07/2023 - 20:42

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,

Thin Force Sensors admin0106 Mon 22/03/2021 - 23:35

Thin variable resistors designed to detect and output real time signals of loads applied from a few tens of grams to a few kg. An ECO-friendly update of the Force Sensing Resistors made recyclable and a bidodegradable core.

We store and distribute on-line these series of standard shapes and sizes and occasionally some successful custom serial productions with varying types of sealing materials and connectors.

We can also quckly design and produce profitable custom series based on your design requirements. Please contact us for more information.

Test your productions

admin0106 Tue 06/04/2021 - 12:49

New productions and prototyping can only be successful if you constantly test your materials, design and productions using appropriate tools and depending on your objectives.

Learn here how to quickly test you productions with a battery and a led but also more interestingly how to test them with a multimeter and how to use microcontroller to acquire related signals.

Circuit Test

When building resistors wand small circuit components with Papier Logik resources, a power source and a led may be enough to test shortcut and relative voltage outputs when resistance values are not too high (below the kOhms order).

This can already lead to a lot of fun and educational applications with little resources but when developing higher levels components such as more complex circuits or sensors, an Ohmmeter or equivalent digital tools should become you friends sooner or later. Here is a collection of good practices and useful information related to securely buildng, testing and specifying you sensors.

Testing with an Ohmmeter

A multimeter is the best tool for detecting shortcuts and measuring conductive materials and resistive sensors. Set as an ohmmeter,

Be aware that you will not read the same value for a component if you test it on the side or if you test it inside a powered circuit.

Testing with an Arduino

An Arduino is the best way to test and use resistive-based sensors, but also to build low-cost oscilloscopes to test materials and used them to build components.

With sufficient output range (e.g. 1k to 100kOms) a Voltage divider makes a simple electronic circuit to plug a resisitve-based sensors. but other techniques can also be of interest.

Then a development with a micro-controller that can be plugged to a computer or another peripheral like an arduino is a great start for building you first Human Interface Device with a variety of applications and efficiency.

Recycling and Reuse

admin0106 Mon 05/04/2021 - 13:35

In chemistry, Lavoisier let a famous french sentence: "Rien ne se perd rien ne se crée, tout se transofrme". Ideend, atoms never disappear in chemistry. It is their electrons that play around with other atoms to break and recreate molecules, which requires or generates various amounts of energies;

So at our scale, it looks like humans and the earth constantly produce and destroy, and the more he consumes energy, the more he changes molecules. But energy is expensive in terms of financial cost, and carbon rates involved, and while not hard to produce, it is hard to store and produce exactly what is being consumed.

It is then esential to minimise the energy consumption through a direct recycling or reuse of our wastes instead of burning or burying them thinking this is not lost anyway.

In the case of papers, according to Canopy Sources it takes half of the water and 2/3rd of the energy to reproduce a recycled paper than to produce a paper made of virgin fibers. You can save 22 trees when producing 1 ton of recycled paper and you will not have to bury or burn paper wastes.

Thus, if paper has to be be produced through sustainble life-cycles, there are many other condictions involved, anddevelopping optimized recycling process, programs and consumers involvments are definitely essential for Sustainbale hardware products life-cycles.

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.

Electrically Functional Paper (and other materials)

admin0106 Wed 31/03/2021 - 12:36

This research field explores the use of paper as a substrate for the production of electronic components and devices. The main goal is to find alternatives to non-renewable and non-recycled substrates used today and especially the synthetic polymers we refer to as plastics.

Paper is a composite material made of refined wood fibers. It has major potentials for being produced through sustainable life-cycles and are notably made of renewable resources thus biodegradable, but also much easier to recycled and much more recycled today than plastics. BUt this point belongs to another research field.

These pages primarily focuse on the scientific and technical research performed to physically and chemical specifications of the papers and the components or devices built from them.
