RFP Title


Partner for Business Using Elastic Electrical Wire ”ROBODEN™”
RFP Description

NineSigma, representing Asahi Kasei Corp. (homepage: ), seeks a business partner that makes use of “ ROBODEN™ ”, the world’s first elastic electrical wire successfully developed by Asahi Kasei.

This electrical wire was developed based on the idea that “an elastic electrical wire without slack will be needed in the future, for wiring in movable parts in industrial robots, humanoid robots, and wearable devices etc.” Asahi Kasei has issued this open request, wishing to solve customers’ wiring problems through joint development with the customer using this elastic electrical wire.

Asahi Kasei is willing to explore new potential markets including relatively small ones.

Key Success Criteria

Characteristics of “ROBODEN”, an Elastic Electrical Wire

 The “ROBODEN” elastic electrical wire has the following characteristics:

  • A structure whereby conductor wires are wound around the elastic body, as illustrated in Figure 1, makes it possible to stretch by approximately from 20% up to 100% compared to the original length.
  • Efficient power and signal transmission is possible owing to copper wire with low electric resistance used as a conductor wire.
  • The parallelly-wound structure of the conductor wire and usage of holding strings allows the following:
    • Good signal transmission (Figure 3)
    • Suppression of local deformation and realization of long life
  • The wire can be customized according to the customer’s specific requirement.

For further details of the elastic electrical wire, please also see the reference below.

Possible Approaches

Anticipated Business Partner

Proposals from organizations that can establish a complementary, mutually beneficial, and cooperative relationship with Asahi Kasei are anticipated, e.g. potential joint development partners such as:

  • Organizations with problems such as “wires becoming slack” and “disconnected wires” inside and outside a device such as products listed in Table 1
  • Organizations seeking a conductor wire for usage in proximity to human bodies which can flexibly follow movements of the human body
  • Other organizations with a technology related to electrical wires, such as connectors and sensors, and that will be able to solve the customer’s wiring problems by making use of ROBODEN
