Validating a Biomechanical Assessment Platform with Inertial Biosensors and Axis Vector Computation | Chapter 3 | Science and Technology - Recent Updates and Future Prospects Vol. 3

 

Human motion capture systems, constructed from Inertial Measurement Units (IMUs), have been the subject of recent development and validation. Inertial kinetics and kinematics have substantial influences on human biomechanical function. Real-time computation of kinematics is essential for delivering prompt results or diagnoses, as well as for applications that necessitate providing feedback to the user, such as correcting a rehabilitation exercise or enhancing an athletic maneuver. A new algorithm for Inertial Measurement Unit (IMU)-based motion tracking is presented in this work. The primary aims of this paper are to combine recent developments in improved biosensor technology with mainstream motion-tracking hardware to measure the overall performance of human movement based on joint axis-angle representations of limb rotation. 

This work describes an alternative approach to representing three-dimensional rotations using a normalized vector around which an identified joint angle defines the overall rotation, rather than a traditional Euler angle approach. Furthermore, IMUs allow for the direct measurement of joint angular velocities, offering the opportunity to increase the accuracy of instantaneous axis of rotation estimations. Although the axis-angle representation requires vector quotient algebra (quaternions) to define rotation, this approach may be preferred for many graphics, vision, and virtual reality software applications. The analytical method was validated with laboratory data gathered from an infant dummy leg's flexion and extension knee movements.

The results showed that the novel approach could reasonably handle a simple case and provide a detailed analysis of axis-angle migration. The invariant combination of the axis-angle representation could open a new era of quantifying biomechanical perception-action systems as interactions with the natural or built environment. The described algorithm could play a notable role in the biomechanical analysis of human joints and offers a harbinger of IMU-based biosensors which may detect pathological patterns of joint disease and injury.

Application of Lab-on-chip (LOC) in Food Safety Sensing: A Review | Chapter 3 | Science and Technology - Recent Updates and Future Prospects Vol. 2

 

This study mainly focuses on the processing, types, and materials used for Lab-on-chip (LOC) fabrication and application of LOC in food safety sensing. When paired with microfluidic techniques, lab-on-chip (LOC) provides an automated, compact platform that enhances analysis for a variety of applications. Using this LOC idea in biosensors makes a variety of analyses easier and faster to detect, particularly when it comes to food safety sensing. Microfluidic chips, also known as lab-on-a-chip devices or microfluidic devices, are miniaturized platforms that manipulate small volumes of fluids, typically in the microliter (10-6 liters) to picoliter (10-12 liters) range. These chips integrate various functions such as sample preparation, analysis, and detection into a single, compact device. The advancement in biosensors to lab-on-chip devices is possible through implementing microfluidics integrated sensing platforms. Microfluidics is an upcoming and novel research area that gives an innovative stream to work with fluid analysis. Channels and Chambers, Manipulation of Fluids, Sample Handling and Preparation, Chemical and Biological Analysis, Point-of-Care Diagnostics, High Throughput Screening, Customizability, and Scalability are the main applications of microfluidics technology on Lab on-chip. Point-of-care diagnostics in food processing is the main focus of this chapter. The processing method and fabrication of lab-on-chip material and some important applications in food safety are discussed in this chapter. There are also some innovative materials like nanomaterials, graphene and conductive polymers along with already known paper based LOC. More technological advancement and research is to be done on LOC based biosensors especially in field of food safety for precise qualitative and quantitative analysis.

Subwavelength Resonant Nanostructures: Fabrication and Functionalities | Book Publisher International

 This Book provides a comprehensive overview of the optical processes in optical nanostructures supporting various resonance excitations and interactions, offering insights into the plasmonic excitations, confined mode propagations, and manipulation of light at the subwavelength scale. By understanding and harnessing these optical processes in resonant nanostructures, researchers can design and develop innovative nanophotonic devices and systems for a wide range of applications, including biosensing, imaging, information processing, energy conversion, and more. This Book is divided into three chapters, each of which focuses on different aspects of optical processes and their applications. The first part of the Book covers nanofabrication and optical characterization of the nanostructures, in particular, a comprehensive range of topics related to cleanroom processes, crystal growth, self-assembly, scanning-electron imaging, and far- and near-field characterization techniques. Readers will gain valuable insights into fundamental cleanroom practices, methods for growing high-quality crystals, techniques for self-assembling nanostructures, and advanced imaging approaches. Additionally, we highlight the cutting-edge far- and near-field characterization methods that enable researchers to analyze materials at the nanoscale with exceptional precision. The second chapter covers the underlying processes of plasmonic applications, including localized resonances, enhanced optical fields, energy localization, quantum plasmonics, and propagating plasmonic surface waves. We provide a brief description of two-dimensional materials and their inclusion in plasmonic nanostructures and their applications. The collective effects in nanoparticle arrays are also discussed, and it is shown how the periodic arrangement of nanoparticles results in narrow resonances with higher quality factors. Finally, the third chapter discusses nanostructure functionalities, including photovoltaics, light sources, sensors, biosensors and chemical sensors, as well as modulators in the context of plasmonics. A detailed explanation of the underlying mechanisms is provided for each application. It serves as a valuable resource for researchers and engineers in the field, guiding them toward harnessing the full potential of resonant optical nanostructures for future applications.
