| Outline of Final Research Achievements |
This research aimed to achieve the creation of electrical circuits in flexible 3D structures and their functional operation (marking and tracing technology for living organisms). Visualization and quantification of position, and evaluation of invasiveness on a wide range of flexible materials. Optimization of dielectric design for instantaneous generation of virtual electrodes and the relationship between bubbles that produce functional interfaces and electric field concentration were clarified. Information embedding for a wide range of sizes and 3D shapes in biological samples with different water content (impedance) was successfully performed to evaluate the sensing capability of the optical magnetic sensor.

| Academic Significance and Societal Importance of the Research Achievements |
３次元造形技術の発展に伴い，多様な材質，形状の物体を短時間かつ簡易に作製することが可能となった現在において, 柔軟性を有する３次元造形物に高解像度かつロバストな電気回路を付与することは産業発展に大きく貢献できる技術と成り得る．一方，従来プラスチック等の非導電性物質への回路形成に使用される無電解めっき法は，事前処理やめっき浴の調整が困難である．事前基板処理・洗浄が不要であり，廃液がほとんど発生せず，金属・ポリマー・生体等，幅広い材質へ配線を行うことのできる本技術はその背景にあるメカニズムや制御性も含めて学術的意義が大変大きい研究である．
