Using sound waves to create a smart T-shirt

Imagine wearing a T-shirt that measures your breathing or gloves that translate your hand movements into commands for your computer. Researchers at ETH Zurich, led by Daniel Ahmed, Professor of Acoustic Robotics for Life Sciences and Healthcare, have laid the foundations for just such smart textiles. Unlike many previous developments in this area, which usually use electronics, the ETH researchers rely on acoustic waves passed through glass fibers. This makes the measurements more precise and the textiles lighter, more breathable and easier to wash. "They are also inexpensive because we use readily available materials, and the power consumption is very low," says Ahmed.

[microwave-waveguides]

Microwave waveguides are crucial components in the field of microwave engineering, facilitating the transmission of high-frequency electromagnetic waves with minimal loss. They are indispensable in a variety of applications, ranging from telecommunications and radar systems to medical equipment and satellite communications. Understanding the intricacies of microwave waveguides can provide valuable insights into their functionality, types, applications, and advantages.

What are Microwave Waveguides?

Microwave waveguides are structures that guide electromagnetic waves, typically in the microwave frequency range, from one point to another. Unlike coaxial cables or transmission lines, which carry both electric and magnetic fields in a dielectric medium, waveguides confine and direct the wave using a hollow metallic or dielectric structure. This confinement leads to higher efficiency and lower loss at microwave frequencies.

Types of Microwave Waveguides

Rectangular Waveguides: The most common type, rectangular waveguides, have a rectangular cross-section. They support the TE (Transverse Electric) and TM (Transverse Magnetic) modes of propagation, with the TE10 mode being the dominant and most efficient one.

Circular Waveguides: These have a circular cross-section and support both TE and TM modes, as well as hybrid modes. Circular waveguides are often used in applications requiring rotational symmetry.

Elliptical Waveguides: Elliptical waveguides are used when the application requires specific polarization characteristics. They are less common than rectangular and circular waveguides but are essential in specialized applications.

Flexible Waveguides: These waveguides are constructed from materials that allow them to bend and flex, making them ideal for applications where rigid waveguides cannot be used due to space constraints.

Ridged Waveguides: Adding ridges inside the waveguide structure can increase the bandwidth and lower the cutoff frequency, making ridged waveguides suitable for wideband applications.

One glass, full color: Sub-millimeter waveguide shrinks augmented-reality glasses

Augmented-reality (AR) technology is rapidly finding its way into everyday life, from education and health care to gaming and entertainment. However, the core AR device remains bulky and heavy, making prolonged wear uncomfortable. A breakthrough from POSTECH now promises to change that. The study is published in the journal Nature Nanotechnology. One of the main hurdles to the commercialization of AR glasses has been the waveguide. In AR optics, the lens itself also serves as a "highway of light," guiding virtual images directly to the user's eye. Due to chromatic dispersion, conventional designs have required separate waveguide layers for red, green, and blue light—three to six stacked glass sheets—inevitably increasing both weight and thickness.

Transmission Speed: Data transport may be slowed down by misalignment.

Signal Quality: Signal loss is decreased by precise alignment.

Network Reliability: Outages and error rates are increased by faulty connections.

Optical Waveguide Alignment System

The Optical Waveguide Alignment System goes beyond conventional alignment, which just considers fibres. It is intended to align integrated photonic waveguides as well as optical fibres, which are crucial parts of photonic chips that manage light-based data transfer on a micro scale.

These systems are necessary in:

Faster, smaller, and more energy-efficient circuits are made possible via silicon photonics.

In quantum computing, accuracy cannot be compromised.

Advanced Sensing: When photonic integration is needed in aeronautical or healthcare applications.

Optical Waveguide Alignment Systems are driving innovation in a variety of sectors by guaranteeing nearly flawless coupling between fibres and waveguides.
