Surface sensors or flexible and stretchable data transfer bus for connection transfer or deformation monitoring

We can develop a serial of flexible surface sensors:
• Deformation monitoring sensor or to pilot robots movments:
• Shocks monitoring:
• Temperature sensors:
• Water leaks or moisture sensor:
• Electrical motor induction current leaks detection conductive grid:

The non-insulated heating Thermotech "NW" yarns (protected by a binder)

Thermotech NW are Thermotech N wires protected by an outside protecting synthetic thread layer that allow easier subsequent textiles of RFID processes:
They remain conductive on surface and allow cross conductivity in cas of yarns crossing in weaving, knitting or embroidery.

Thermoflex NW: stainless ultra fine micro multi-filaments threads family

Properties:

• Protected by a thin protecting wrapping to facilitate subsequent textile transformation processes.
• Good flexibility
• High mechanical and thermal fatigue withstanding.
• Constant conductivity with or without mechanical stress.
• Special micro multi-filaments structure , existing in several thicknesses
  • 0,05 gr/m (50 tex), electrical resistivity of 130 Ohms/meter
  • 0,10 gr/m (97 tex), electrical resistivity of 68 Ohms/meter
  • 0,15 gr/m (150 tex), electrical resistivity of 45 Ohms/meter
  • 0,28 gr/m (280 tex), electrical resistivity of 30 Ohms/meter
• High mechanical strength.
• High temperature resistant: up to 600°C, or even more when they are protected from oxidation (neutral environment).
• Outstanding performances for RFID applications, with a very good resistance to industrial washings.
• Great resistance to sweat, oxidation, salty water and industrial washing.

Stretchable condustretch narrow bands with several conductive elements are allowing off-set connections or to be linked to machine in movement or other robots:
• Deformation monitoring sensor or to pilot robots movments:

Condustretch and Thermostretch: elastic narrow ribbons with integrated conductive or heating wires

Narrow elastic ribbon Condustretch are perfectly adapted to sensor connexions, data or energy transfers within washable or composite parts:

• Can help to pre-position the connections within thermoplastic flat parts which will later undergo thermoforming or press-forming.
• A version exists with several conductive yarns in parallel which makes a data bus elastic in all directions (contrary to "flex" electronics circuits).
• They are well adapted to sport or medical clothes or for robotics.
• Specific versions with controlled elongation are adapted to strain monitoring.
• Connection within washable clothes is one of the main applications of the Condustretch.


Thermostretch heating elastic ribbons are similar to Condustretch but adapted to heating applications:

• "N" non insulated or "I" insulated versions exist.
• Designed for low voltage (3 to 24 volts).
• Can easily be integrated within clothes or other flexible heating structures.

Tungsten multi-filaments for heating, cutting or high temperature applications:

These thin heating yarns are manufactured from metal complex which includes Tungsten.

These yarns are characterized by:

• High mechanical resistance especially at high temperatures
• Maximum melting point temperature around 3400°C
• Very low thermal expansion factor
• Standard diameter: 25 micrometres
