Abstrak :
This book provides a comprehensive theoretical and practical review of biomimetic materials with self-healing, self-lubricating and self-cleaning properties. These three topics are closely related and constitute rapidly developing areas of study. The field of self-healing materials requires a new conceptual understanding of this biomimetic technology, which is in contrast to traditional engineering processes such as wear and fatigue. A new theoretical framework for these processes is presented based on the concept of multi-scale structure of entropy and non-equilibrium thermodynamics, together with a detailed review of the available technology. The latter includes experimental, modeling, and simulation results obtained on self-healing/lubricating/cleaning materials since their emergence in the past decade.

Abstrak :
ROV (Remotely Operated Vehicle) adalah sebuah piranti nirawak yang dimanfaatkan untuk melakukan berbagai pekerjaan di bawah air (underwater), salah satunya adalah pemetaan bawah laut (seabed mapping). Pemetaan bawah laut krusial untuk dilakukan dalam membantu penerapan sistem Ina-TEWS (Tsunami Early Warning System). ROV yang cocok untuk melakukan pekerjaan tersebut adalah ROV yang memiliki kemampuan jelajah yang luas dengan efisiensi penggunaan energi yang tinggi. Beberapa tahun belakangan ini, konsep biomimikri sudah cukup banyak diterapkan ke dalam piranti ROV demi menghasilkan desain dan geometri ROV yang lebih efisien dengan memanfaatkan fitur fitur alamiah dari makhluk hidup. Penerapan bentuk ikan pari/manta ray (M. Birostris) dinilai dapat memberikan keunggulan dalam energy conservation ROV, dengan memanfaatkan gliding effect yang jika dianalogikan menyerupai efek layang layang di bawah air. Angle of attack adalah sudut antara garis referensi pada benda dan vektor yang mewakili gerakan relatif antara benda dan fluida yang dilaluinya. Angle of attack berpotensi untuk dijadikan variabel penelitian untuk mengetahui hambatan total pada ROV yang disimulasikan. Tujuan penelitian ini adalah untuk menganalisis hambatan total dari ROV Biomimikri Manta Ray serta melakukan perbandingan terhadap hambatan total dari ROV Market Bluefin 21. ROV Biomimikri Manta Ray dibuat dengan desain model 0°, 5°, 10°, dan 15°. Model sudut dibuat berdasarkan sudut pada pectoral fins desain model ROV Biomimikri Manta Ray. Pengujian juga dilakukan berdasarkan 3 variasi angle of attack yakni 0°, 3°, dan 6°, dengan kecepatan/speed range 0 sampai 6 knot, dan interval 0.5 knot. Pengujian dilakukan secara numerik dengan software CFD (Computational Fluid Dynamics) NUMECA FINE Open. Penelitian ini diharapkan dapat membantu menganalisis perbandingan hambatan total ROV Biomimikri dan ROV Market dengan variasi angle of attack terhadap hambatan total yang dihasilkan. ......ROV (Remotely Operated Vehicle) is an unmanned device that is used to perform various underwater tasks, one of which is seabed mapping. Underwater mapping is crucial to be carried out in assisting the implementation of the Ina-TEWS system (Tsunami Early Warning System). The ROV that is suitable for doing this work is an ROV that has a wide cruising capability with high energy efficiency. In recent years, the concept of biomimicry has been widely applied to ROV devices in order to produce a more efficient ROV design and geometry by utilizing the natural features of living things. The application of the form of a stingray/manta ray (M. Birostris) is considered to be able to provide advantages in energy conservation ROV, by utilizing the gliding effect, which is analogous to the effect of a kite under water. The angle of attack is the angle between the reference line on the object and the vector that represents the relative motion between the object and the fluid in its path. Angle of attack has the potential to be used as a research variable to determine the total resistance of the simulated ROV. The purpose of this study was to analyze the total resistance of the Manta Ray Biomimicry ROV and to compare the total resistance of the Bluefin 21 ROV Market. The Manta Ray Biomimicry ROV was made with model designs of 0°, 5°, 10°, and 15°. The angle model is based on the angle on the pectoral fins of the Manta Ray Biomimicry ROV model design. Tests were also carried out based on 3 variations in angle of attack, namely 0°, 3°, and 6°, with a speed range of 0 to 6 knots, and an interval of 0.5 knots. The test was carried out numerically with the NUMECA FINE Open CFD (Computational Fluid Dynamics) software. This research is expected to help analyze the comparison of the total resistance of ROV Biomimicry and ROV Market with variations in angle of attack to the resulting total resistance.

This book brings together first-hand knowledge from the frontiers of different fields of research in sensing. The topics presented cover a broad spectrum ranging from energy transformation and transduction processes in animal sensing systems to the fabrication and application of bio-inspired synthetic sensor arrays. The various contributions are linked by the similarity of what sensing has to accomplish in both biology and engineering.

Abstrak :
Biomateriomics specifically focuses the analysis of the role of materials in the context of biological processes, the transfer of biological material principles towards biomimetic and bioinspired applications, and the study of interfaces between living and non-living systems. Applying biomateriomics can unlock Nature’s secret to high performance materials such as spider silk, bone, and nacre, and elucidate the progression and diagnosis or the treatment of diseases. Similarly, it contributes to develop a de novo understanding of biological material processes and to the potential of exploiting novel concepts in innovation, material synthesis and design.

A significant proportion of modern medical technology has been developed through biomimetics, which is biologically inspired by studying pre-existing functioning systems in nature. Typical biomimetically inspired biomaterials include nano-biomaterials, smart biomaterials, hybrid biomaterials, nano-biocomposites, hierarchically porous biomaterials and tissue scaffolds. This important book summarises key research in this important field. The book is divided into two parts, part one is devoted to the biomimetics of biomaterials themselves while part two provides overviews and case studies of tissue engineering applications from a biomimetics' perspective. The book has a strong focus on cutting edge biomimetically inspired biomaterials including chitin, hydrogels, calcium phosphates, biopolymers and anti-thrombotic coatings. Since many scaffolds for skin tissue engineering are biomimetically inspired, the book also has a strong focus on the biomimetics of tissue engineering in the repair of bone, skin, cartilage, soft tissue and specific organs. With its distinguished editor and international team of contributors, Biomimetic biomaterials is a standard reference for both the biomaterials research community and clinicians involved in such areas as bone regeneration, skin tissue and wound repair.
