RFP Title


Non-Destructive  Sensing to Measure Body Contents of Bivalves
RFP Description

NineSigma, representing a global manufacturer, seeks a non-destructive sensing technology to measure body contents of bivalves (oysters) from outside the shell, in order to evaluate their filled state. The client welcomes a wide range of proposals, including those that have not been applied to the fishery products yet, but, in principle, will likely be through additional development.

Key Success Criteria

Prerequisites: Details of bivalves to be measured

  • Type of bivalves: Oysters
  • Size of the shell: 60–130 mm in length × 30–70 mm in breadth × 14–45 mm in height
  • Thickness of the shell: Up to 5 mm
  • Weight: 35–140 g
  • Body contents should be rich in water and glycogen.
  • The current approach to measure the filling state includes random visual inspection of shucked oysters, as well as removal of oysters using the following equation: Condition index = Dry weight of the body contents / (Total weight − Dry weight of the shell) × 1,000 = 50 or less:
    • Since glycogen contents play a role in checking the filling state, an equation using dry weight of the body contents, as described above, is used.



Requirements of the technology

  • The technology should lead to collection of the following data by measuring body contents of bivalves (oysters) from outside the shell in a non-destructive manner:
    • Data that has correlation with the above condition index
    • Estimated dry weight of the body contents
  • Measurement accuracy: Ideally, the consistency between the condition index estimated by the technology and the actual condition index should be at least 99%.
  • Measurement time: 1 minute or less per oyster, and ideally, 4 seconds or less.



Possible Approaches

Possible approaches might include, but are not limited to, the following. Proposals for a technology that will likely meet the requirements are widely expected to participate.

  • Near-infrared spectroscopy
  • Nuclear magnetic resonance spectroscopy
  • Terahertz radiation
  • Soft x-ray radiation
  • Ultrasonic measurement


The client has attempted to develop the technology using approaches, such as soft X-ray radiation and near-infrared spectroscopy; however, the following problems arose. Therefore, proposals for a technology that can solve these problems, even though the same approaches are used, are especially anticipated.

  • Soft X-ray radiation: When X-rays strong enough to pass through the shell, the body looked completely transparent because the shell can absorb X-rays more easily than the body.
  • Near-infrared spectroscopy: The same kind of problem as the above occurred.



Approaches Not of Interest

The following approaches are not of interest:

  • Approach that requires drilling a hole in a shell
  • Evaluation by weight measurement of the entire bivalve




The client is a global manufacturer that conducts aquaculture business with oysters and other bivalves. Since the commercial value of these bivalves depends on the filling state of their body contents, the client wishes to evaluate the filling state before shipment, without opening the bivalve or drilling a hole in the shell.


While the client has used various approaches, including soft X-rays and near-infrared spectroscopy, some problems arose. In the case of evaluation using soft X-rays, for instance, when X-rays strong enough to pass though the shell were irradiated, the body looked completely transparent because the shell can absorb X-rays more easily than the body.


Therefore, for early resolution of these problems, the client has issued this open request to find a potential development partner as soon as possible.



Items to be submitted

NineSights, the platform of NineSigma’s Open Innovation community, allows you to manage all your proposals. Please contact the Solution Provider Help Desk for assistance about registration and proposal submission.

Proposal may include the following items along the response form shown by clicking the “Respond” button.

  • Overview, principle, and uniqueness of the technology
  • Development stage (Concept level / Lab level verification / Under development for practical use / Already commercialized)
  • Current performance of the proposed technology
    • Objects to be measured
    • Size and weight of the objects
    • Shell thickness of the objects (if there have shells)
    • Accuracy of the sensing technology
    • Measurement time per one object
  • Conditions for sample testing using bivalve (oysters) sample (cost, period, necessity of an NDA, etc.)
  • Current challenges and future plans
  • Track records (e.g. additional information supporting the R&D capabilities, such as research papers and patents)
  • Organization overview



Notes on Response

Proposal shall have clear points and should not include confidential information. Supplemental files may be submitted in addition to the proposal.



Anticipated Project Process

After reviewing submitted proposals, the client possibly ask clarifying questions before selecting the most suitable candidates for collaboration. The client will select best candidates through evaluations. During the selection process, the client may execute NDA with selected respondents, seek further information disclosure, and discuss specific development targets or potential opportunities.

The client will execute necessary agreements with the selected respondents and move to the advanced development phase. Specifics of any collaboration will be determined through consultation with the concerned parties.



Response evaluation

The client will evaluate all responses with the following criteria.

  • Overall scientific and technical merit
  • Approach to proof of concept or performance
  • Economic potential of concept
  • Realism of the proposed plan (action items, timeline, roles, deliverables, cost estimation)
  • Potential for proprietary position
  • Respondents’ capability and related experiences
