Research paper : Development of flexible-printable device processing technology (T. Kamata et al.)−183 Synthesiology - English edition Vol.1 No.3 (2009) We believe that the greatest significance of our prototype was to show the validity of technology, that sufficient performance could be obtained when technologies are used in set. We were able to appeal the attractive point of technology that we could create things that we never saw before (Figure 10).It is uncertain whether the prototype itself will be taken up by companies for final product realization. However, we think delivering messages will contribute greatly to corporate decisions of whether to employ these technologies as targets of realization.5 Future issues and developmentsAs described above, the field of information terminal technology to which printable device processing technology is being applied has characteristic of becoming more branched as it diffuses further into the society and the required technological specification becomes diverse. If one jumps into development to meet each and every demand, there will be as many technologies as demands, and strategic, planned technological development becomes impossible. As effort to be strategic, we placed particular emphasis on planar and continuous aspects of future technological development.5.1 Set of technologies and timingFor industrial technology today, it is extremely difficult to achieve technological concept with single technology. In many cases, technologies from different fields are required to supplement development. In case the target is current and the developed technology is intended to replace current technology, it is probably not necessary to pay attention to related technologies. However, in case the goal is new technology that may lead to creation of new market, that is, if it is pioneering technology, it is mandatory to pay attention to combination with other technologies, and build a technological system. Therefore, planar development or development of set of technologies is important.There is one important point that must not be forgotten. That is the concept of development phase or knowing where the currently developed technology is positioned. Grouping technologies into set is routine, and companies that engage in development as business do so regularly. However, when time concept of development phase is considered, one realizes that it is not a singular concept. The company starts grouping technologies into set only when the technology is near completion and enters the phase when the overall scenario becomes visible. Even a company must struggle with a single technology for which the scenario is unclear, and must wait a while before the scenario can be written.Another point is that to aim at target that couldn’t group technologies into set because there was “gap in technology.” This means that the technologies could be bundled together only after development of new technology. Since this often leads to new products and new industry, it is worth working hard. In corporate activity, when gap occurs in area outside the company’s technological domain, nothing can be done and the development may have to be given up.Therefore, the issue is who will be the first to present the scenario for industrial development. For industrial technology, the key point is to discern which is technology that is likely to win, and that is what we pursued.5.2 Continuous development leads to early diffusionMoreover, continuous development of technology, or pioneering of next technology, is very important. How technology is developed as industrial technology under which scenario is extremely important for realization. It is particularly important in our field where technological development tends to be single shot. Single-shot technology may be useful to meet special demand but its wide diffusion may be difficult. On the other hand, showing the second and third hands for technology that others find interesting presents the depths of the technology and is useful in drawing more attention. As result, speed of diffusion into the industry will increase for related technologies. That is why it is important to continue pioneering technology and to present scenario of how the technology will grow.(29)−Fig. 9 Development of flexible transpiration sensor for agricultural use.Fig. 10 Scenario for realization of flexible printable electronics.Publicity through press release, etc.Deliver message of conceptDemonstrate device operation and prove efficacy of technology by showing that it functions as requiredDemonstration of operationJoint research with owner of technologyOptimization of material, device structure, and manufacture processMatch between process condition and required performance for proper functioningDevelopment of elemental technologyMarket survey, academic surveyExtraction of required performanceDevice designExtraction of final user demand (functions used and environment)Survey of user demandScenario for goal realization
