developing tactile wood materials woodoo and altium

What is Tactile Wood?

Tactile wood refers to engineered wood materials that have been designed to provide enhanced tactile properties compared to natural wood. These materials aim to deliver a more engaging sensory experience through their texture, warmth, and overall feel.

Two prominent examples of tactile wood materials are Woodoo and Altium. Both offer unique approaches to enhancing the tactility of wood while maintaining or improving its strength, durability, and sustainability.

Woodoo: Transparent & Tactile Wood Material

Woodoo is a French startup that has developed a patented process for transforming wood into a translucent, tactile material. Their technology involves treating wood with a proprietary bio-based polymer that replaces the lignin and air in the wood’s cellular structure.

The resulting material, also called Woodoo, has several remarkable properties:

Translucency: Woodoo allows light to pass through, creating a unique visual effect while maintaining the wood grain pattern.
Tactility: The bio-polymer imparts a smooth, silky texture to the wood surface, making it inviting to touch.
Strength: Woodoo is 3 times stronger than natural wood and has greater resistance to humidity and fire.
Sustainability: The Woodoo process uses fast-growing wood species and bio-based polymers, making it an eco-friendly alternative to plastic and other synthetic materials.

Potential applications for Woodoo include furniture, interior design elements, automotive interiors, consumer electronics, and more. The company has already partnered with major brands like Chanel, Yamaha, and Hermès to explore incorporating Woodoo into their products.

Altium: Haptically-Enhanced Wood Surfaces

Altium is a research project led by the Human-Computer Interaction group at Aalto University in Finland. Their focus is on developing wood surfaces with enhanced haptic feedback through embedded electronics.

The Altium approach involves integrating thin, flexible electronic circuits into wood veneers. These circuits can detect touch and gestures, as well as provide tactile feedback through vibration or slight surface deformation.

Some potential applications for Altium’s haptically-enhanced wood surfaces include:

Interactive furniture: Tables or shelves that respond to touch, providing information or controls.
Assistive devices: Tactile guidance systems for the visually impaired, using wood surfaces in public spaces.
Artistic installations: Interactive wooden artworks that engage the sense of touch.

By combining the natural warmth and texture of wood with the interactivity of embedded electronics, Altium aims to create more intuitive and engaging interfaces for a variety of contexts.

The Science Behind Tactile Wood

Woodoo: Transforming Wood Structure

The Woodoo process leverages the natural cellular structure of wood to create its unique properties. Wood is composed of cellulose fibers bound together by lignin, with air-filled spaces (lumens) in between.

Woodoo’s bio-polymer treatment involves the following steps:

Extraction: The lignin is selectively removed from the wood using a proprietary extraction process. This step also removes the air from the lumens.
Impregnation: The wood is then impregnated with Woodoo’s bio-based polymer, which fills the spaces left by the extracted lignin and air.
Stabilization: The polymer is stabilized within the wood structure, creating a strong, durable matrix.

The bio-polymer used by Woodoo is transparent, allowing light to pass through the treated wood. It also provides a smooth, tactile surface that is pleasant to touch.

Altium: Integrating Electronics into Wood

Altium’s approach to tactile wood involves the integration of thin, flexible electronic circuits into wood veneers. This process requires careful consideration of the materials and fabrication methods to ensure compatibility and durability.

The key steps in creating Altium’s haptically-enhanced wood surfaces are:

Circuit design: Thin, flexible circuits are designed to detect touch, gestures, and provide haptic feedback. These circuits are typically made of conductive polymers or metallic nanomaterials.
Veneer preparation: Thin wood veneers are selected and prepared for circuit integration. The veneers must be smooth, uniform, and free of defects.
Circuit integration: The flexible circuits are bonded to the wood veneer using a combination of heat, pressure, and adhesives. The goal is to achieve a seamless integration without compromising the wood’s appearance or tactile properties.
Lamination: Multiple layers of circuit-embedded veneers can be laminated together to create thicker, more robust wood surfaces.

The resulting haptically-enhanced wood surfaces can detect various types of input and provide tactile feedback to the user. For example:

Interaction	Detection	Feedback
Touch	Capacitive sensing	Vibration
Gesture	Proximity sensing	Surface deformation
Force	Pressure sensing	Resistance

By integrating electronics into wood, Altium aims to create more intuitive and engaging interfaces that leverage the natural warmth and texture of the material.
