"This book analyses the state of the art of piezoelectric nanomaterials and introduces their applications in the biomedical field. Despite their impressive potentials, piezoelectric materials have not yet received significant attention for bio-applications. This book shows that the exploitation of piezoelectric nanoparticles in nanomedicine is possible and realistic, and their impressive physical properties can be useful for several applications, ranging from sensors and transducers for the detection of biomolecules to “sensible” substrates for tissue engineering or cell stimulation.

"This book introduces physical effects and fundamentals of piezoelectric sensors and actuators. It gives a comprehensive overview of piezoelectric materials such as quartz crystals and polycrystalline ceramic materials. Different modeling approaches and methods to precisely predict the behavior of piezoelectric devices are described. Furthermore, a simulation-based approach is detailed which enables the reliable characterization of sensor and actuator materials.
One focus of the book lies on piezoelectric ultrasonic transducers. An optical approach is presented that allows the quantitative determination of the resulting sound fields. The book also deals with various applications of piezoelectric sensors and actuators."

"This book presents an overview of the ways in which the latest experimental and theoretical nanotechnologies are serving the fields of biotechnology, medicine, and biomaterials. They not only enhance the efficiency of common therapeutics and lower their risks, but thanks to their specific properties, they also provide new capabilities. Nano-scale measurement techniques, such as nano-indentation and nano-scratch methods, could potentially be used to characterize the physical and mechanical properties of both natural tissues and synthetic biomaterials in terms of strength and durability."

"Biomedical foams are a new class of materials, which are increasingly being used for tissue engineering applications. Biomedical Foams for Tissue Engineering Applications provides a comprehensive review of this new class of materials, whose structure can be engineered to meet the requirements of nutrient trafficking and cell and tissue invasion, and to tune the degradation rate and mechanical stability on the specific tissue to be repaired.
Part one explores the fundamentals, properties, and modification of biomedical foams, including the optimal design and manufacture of biomedical foam pore structure for tissue engineering applications, biodegradable biomedical foam scaffolds, tailoring the pore structure of foam scaffolds for nerve regeneration, and tailoring properties of polymeric biomedical foams.
Chapters in part two focus on tissue engineering applications of biomedical foams, including the use of bioactive glass foams for tissue engineering applications, bioactive glass and glass-ceramic foam scaffolds for bone tissue restoration, composite biomedical foams for engineering bone tissue, injectable biomedical foams for bone regeneration, polylactic acid (PLA) biomedical foams for tissue engineering, porous hydrogel biomedical foam scaffolds for tissue repair, and titanium biomedical foams for osseointegration."

"Kebutuhan akan energi semakin meningkat. Saat ini, lebih banyak yang menggunakan sumber daya alam terbatas sebagai penghasil energi, seperti solar, bensin, batubara dan lain-lain sehingga banyak peneliti yang mengembangkan energi alternatif dari sumber daya alam yang dapat diperbarui, seperti gelombang laut, angin, matahari, getaran, dan piezoelektrik. Namun, penelitian mengenai piezoelektrik masih sedikit. Oleh karena itu, penulis mencoba untuk menganalisis gelombang tegangan keluaran piezoelektrik sehingga dapat dilihat bentuk serta pemanfaatannya.
Penelitian ini merupakan penelitian kualitatif yang menganalisis gelombang tegangan piezoelektrik. Pengambilan data dilakukan dengan menempelkan piezoelektrik pada dinding, kemudian memukulnya menggunakan silinder pemukul yang dipasang pada sebuah motor sehingga ketika motor berputar, silinder pemukul akan mengenai piezoelektrik. Rangkaian ini kemudian dihubungkan dengan osiloskop untuk melihat gelombang yang dihasilkan.
Hasilnya adalah gelombang tegangan yang dihasilkan berbentuk sinusoidal (bolak-balik ; AC) dengan gelombang positif lebih besar dibanding dengan gelombang negatifnya yang dikarenakan besar momentum tumbukan lebih besar dibanding regangan. Tegangan yang dihasilkan oleh piezoelektrik berpengaruh terhadap dimensi (luas penampang dan tebal) dari piezoelektrik.

The demand for energy is increasing. Nowadays, people often useunrenewable resources as energy, such as diesel, gasoline, coal and other so researchers are developing alternative energy from renewable resources, such as ocean waves, wind, solar, vibration, and piezoelectric. However, research on piezoelectric still small. Therefore, the author tries to analyze the piezoelectric output voltage waveform that can be seen form and utilization.
This research is a qualitative study that analyzed the piezoelectric voltage waveform. Data retrieval is done by attaching a piezoelectric on the wall, then hit him using cylindrical bat mounted on a motor so when the motor spins, the piezoelectric cylinder will bat. The circuit is then connected to an oscilloscope to see the waveform generated.
The result is a surge voltage generated sinusoidal (Alternating Current) with positive waves greater than the negative waves that because large momentum pressure greater than strain. The voltage generated by the piezoelectric effect on the dimensions (cross-sectional area and thickness) of the piezoelectric.

"Nanomaterial technologies can be used to fabricate high-performance biomaterials with tailored physical, chemical, and biological properties. They are therefore an area of interest for emerging biomedical technologies such as scaffolding, tissue regeneration, and controlled drug delivery. Nanomaterials in tissue engineering explores the fabrication of a variety of nanomaterials and the use of these materials across a range of tissue engineering applications.
Part one focuses on the fabrication of nanomaterials for tissue engineering applications and includes chapters on engineering nanoporous biomaterials, layer-by-layer self-assembly techniques for nanostructured devices, and the synthesis of carbon based nanomaterials. Part two goes on to highlight the application of nanomaterials in soft tissue engineering and includes chapters on cardiac, neural, and cartilage tissue engineering. Finally, the use of nanomaterials in hard tissue engineering applications, including bone, dental and craniofacial tissue engineering is discussed in part three.

"This book presents a thorough discussion of the physics, biology, chemistry and medicinal science behind a new and important area of materials science and engineering: polymer nanocomposites. The tremendous opportunities of polymer nanocomposites in the biomedical field arise from their multitude of applications and their ability to satisfy the vastly different functional requirements for each of these applications. In the biomedical field, a polymer nanocomposite system must meet certain design and functional criteria, including biocompatibility, biodegradability, mechanical properties, and, in some cases, aesthetic demands.
