Active materials represent a research area with applications spanning both the commercial and military sectors. Some widely recognized active materials are piezoelectric (electromechanical coupling), magnetostrictive (magneto-mechanical coupling), and shape-memory alloys (thermo-mechanical phase-transformation coupling). Many of the physical phenomena associated with bulk active materials are well known. Historically, this research area has been focused on bulk materials (i.e. greater than 50 microns) development/characterization for structural applications rather than thin films systems. For reference purposes, piezoelectric research developed in the 1950’s (i.e. PZT), while Nitinol (i.e. shape memory) and Terfenol-D (i.e. magnetostrictive) developmental efforts began in the 1960’s. In the late 1970’s integration of these bulk active materials into smart systems for reducing vibration (e.g. rotorcraft active control flap), minimizing optical aberrations (e.g. Hubble telescope), and precision positioning objects (e.g. commercial cannon auto-focus camera) achieved considerable success. Much of the fundamental research spurred development of new active materials such as ferromagnetic shape memory alloys, active polymeric systems, and multiferroic materials. While these areas represent major research advancements, the integration of these materials into the small scale began during the last decade, i.e. small scale thin films being defined by dimensions less than 10 microns, hence Thin Film materials. Such novel active thin film materials will have a significantly larger impact on future Sensor and advanced device technology than their active material predecessors (the macro active materials) had on previous structural applications. Therefore, active thin films represent both an important and an enabling technology for a number of future sensor applications.
This special issue will include original papers focused on, but not limited to the following topics:
• Novel thin film active materials; uniform composition to complex multi-layers; property tunability
• Film deposition, process science, modeling, and property optimization
• Film deposition/fabrication and compatibility with substrate
• Processing science of hetero-structure active thin film materials
• Characterization/measurement methodologies of materials properties, and standardization
• Compatibility of film constituents; Integration, constituent compatibility, design and material property tuning for system applications
• Development and processing of complex multi-layer hybrid active thin film devices/structures
• Development of complex and hybrid film systems
• Improvement/optimization of the active thin film properties (Specifications and nomenclature and quality tests are vital appropriate frame work for active thin film materials characterization and optimization)
• Active material-Improvement in sensor design
• Integration (design and integration engineering: process design and control, structure, microstructure, surface and film/substrate engineering and assessment of thin film materials)
• Materials reliability (test and evaluation); accelerated lifetime testing
• Material property tuning for system sensor application
• Concept and technology demonstration (CTD) to support decision for transition to system development and demonstration.
• Technology investment strategy and future material and sensor trends. Future trends associated with the development and potential uses of thin-film active materials for sensors applications
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed Open Access monthly journal published by MDPI.
