Skin-Like Microfiber Grating Gauges Cardiovascular Wellness
According to the World Health Organization, 17.9 million people die annually due to cardiovascular diseases. Soft wearable devices are well suited for monitoring physiological signals from electrocardiogram, phonocardiogram, and pulse wave. Advantages of these types of devices include real-time operation capability, skin-like mechanical properties, and high signal-to-noise sensing capability.

However, monolithic hemodynamic parameters achieved by current wearable devices cannot adequately and precisely reflect the health status of regional vasculature. Spatiotemporal hemodynamic monitoring techniques are needed to satisfy growing demand for clinical treatment and daily health management of the cardiovascular system.

Perovskite Cells Meet Wearable Biosensor’s Power Demands
Perovskite solar cells are providing a team at Caltech’s Heritage Medical Research Institute with an efficient power source for wearable sweat sensors that monitor a host of biomarkers associated with disease diagnostics and fitness levels. The Caltech researchers have collaborated with a group at Johannes Kepler University Linz (Austria) to power the wearable biosensors with the flexible perovskite solar cells (FPSCs).

The wearable device itself is assembled in an origami-like fashion, with individual layers dedicated to different processes. The FPSCs provide ample power under outdoor and indoor illumination conditions, enabling the sensors to periodically monitor sweat rate and continuously monitor numerous biomarkers.

Pixel-by-Pixel, Detector Captures Far-Away Targets in all Conditions
The capability to detect and track small, moving objects remotely, in all conditions, is crucial to many surveillance and monitoring missions. It is also an ongoing challenge.

According to Tian Ma, a computer scientist at Sandia National Laboratories, the greatest challenge for physical security surveillance is often caused by objects that are located far away from sensors, which appear much smaller than their actual physical dimensions. Sensor sensitivity diminishes as the distance from the target increases; when a target object is located far away from the sensor, it has a low signal-to-noise ratio (SNR), which makes it more difficult to detect. The limit of detection for remote sensors is bounded by what can be observed on a...]]>

Sensor Uses Color Encoding for 3D Scene Reconstruction
Researchers at the National University of Singapore (NUS) developed a light-field sensor that detects 3D light fields across the x-ray to visible light spectrum. The sensor relies on a pixelated color conversion strategy that is based on perovskite nanocrystal arrays.

The color conversion strategy developed by the researchers further supported absolute spatial positioning, 3D imaging, and visible light and x-ray phase-contrast imaging in addition to 3D light-field detection.

Current light-field detection techniques either require complex microlens arrays or are limited to the ultraviolet (UV) to visible wavelength ranges. The ability to detect light direction beyond optical wavelengths, using color-contrast encoding, could be...]]>

By the Numbers: Photon Counting and Number Resolution
Light transmits information about its emitter (source) and the medium of propagation. If this information is relevant, the light can be detected for analysis — and it has been detected with increasing levels of sensitivity and resolution over the years. Today’s detectors have the ability to achieve single-photon resolution. Putting such capabilities into practical application is still not a trivial task, however, and can benefit from a deeper understanding of the principles of detection and single-photon resolution.

Over time, engineers have designed a multitude of photonic detection systems. For example, a spectroscopic system determines intensity as a function of wavelength, while an imaging system acquires a...]]>

Photovoltaics Power an Indoor Revolution
Readers of a certain age may recall getting through math and science courses with the assistance of a trusty solar-powered calculator that could harvest just enough ambient light from the classroom to power its rudimentary electronics and LCD screen. For many years, such devices were something of an anomaly in an otherwise wall plug- and battery-powered world, where most gadgets were too sophisticated to get by with just a few microamps of light-generated current.

Machine Learning Reduces Drift in Fiber Sensors
Using machine learning and an established mathematical model, scientists at the National Institute of Standards and Technology (NIST) developed a machine learning-based algorithm to predict drift in existing fiber Bragg grating (FBG) temperature sensors. The algorithm could be used to reduce the effect of drift without the need to purchase or develop new sensor technology.

“It’s an alternative approach where you can have your cake (keep the existing technology) and eat it too (reduce the contribution of long-term drift),” researcher Zeeshan Ahmed said. “Fiber Bragg-grating sensors are cheap. Rather than spending five years to develop better materials, why not just use this algorithm, or a similar one in this...]]>

Flow Cytometry Technique Shows Promise for Early Cancer Diagnosis
A digital droplet microfluidic flow cytometry technique could enable earlier recognition of tumor development and progress, by aiding in the detection of multiple microRNAs (miRNAs) in single circulating tumor cells (CTCs). Tumor-associated miRNAs within CTCs are considered biomarkers for tumor growth.

According to the research team behind the technique, current CTC detection strategies that are based on surface epithelial markers exhibit low specificity in distinguishing between CTCs and epithelial cells in hematopoietic cell populations. So far, it has been challenging for scientists to devise a way to perform in situ analysis of multiple miRNAs of single living CTCs.

In the recent work, the team led by professor Chen Yan...]]>

Optogenetic Tools Use Blue Light to Restore Cell Function
Researchers from the University of Cincinnati (UC), the University of Illinois Urbana-Champaign (UI), and the University at Buffalo (UB) used an optogenetic technique to bring together mitochondria and lysosomes in human stem cells, to revitalize the cells’ fission process.

Mitochondria are dynamic organelles that constantly undergo the processes of fission — separating — and fusion — coming together— in healthy cells. An imbalance in these processes can lead to neurodegenerative diseases such as dementia and certain cancers.

Previous research showed that lysosomes, another type of organelle, can induce mitochondrial fission. Once they are brought in contact with mitochondria, lysosomes act like...]]>

Clinicians Turn to Unobtrusive Sensors for Patient Monitoring
Researchers at the University of South Australia developed a multimode optical fiber (MMF) sensor array to unobtrusively monitor the movement and vital signs of patients in hospitals and other health care settings. The sensors, which are designed to be embedded in the upper portion of a patient’s mattress, could help prevent falls, reduce bedsore injuries, monitor respiration rates, and otherwise improve health outcomes for patients while reducing the need for manual monitoring.

An array of seven MMF cables comprises the smart bed sensor, bundled at the sensor’s input and output locations. The bundled fiber ends are mounted for the positioning of a laser beam and camera; a single laser light source and a single camera are...]]>
