Electrical pumping, which involves injecting a current to generate a population inversion, is challenging to achieve in organic...]]> https://www.photonics.com/Articles/OLEDs_Could_Be_Solution_to_Electrically_Driven/a69376 A69376 Fri, 06 Oct 2023 07:00:00 GMT
Postpartum hemorrhage, the leading and most preventable cause of maternal mortality, can be hard to detect, because physiological compensation mechanisms can mask excessive bleeding. In the early stages of hemorrhage, the sympathetic nervous system becomes activated to ensure adequate perfusion of vital organs and, in turn, vital signs remain stable.

Worldwide, the most common methods of diagnosing postpartum hemorrhage are visual estimation of blood loss or monitoring of vital signs. Blood loss is routinely underestimated beyond the point of early intervention.

To diagnose postpartum hemorrhage in its early stages, a multidisciplinary research team at Washington University in St. Louis developed a wearable optical device that...]]> https://www.photonics.com/Articles/Wearable_Sensor_Could_Lower_Mortality_Due_to/a69365 A69365 Tue, 03 Oct 2023 07:00:00 GMT

A multispectral, super-low-dose photoacoustic microscopy (SLD-PAM) system developed by City University of Hong Kong (CUHK) achieves significantly higher sensitivity than traditional optical resolution photoacoustic imaging.

By providing an exceptionally high level of sensitivity, SLD-PAM could help broaden the use of photoacoustic microscopy in biomedical applications. In the future, it could translate to clinical settings; for example, it could be used for ophthalmic exams where a low-power laser is preferred for the patient’s safety and comfort. Long-term monitoring of pharmacokinetics or blood flow also requires low-dose imaging to alleviate perturbation to tissue function.

Researchers at the Department of Energy’s Oak Ridge National Laboratory (ORNL) have created a detection system that allows home energy auditors to see air leaking from a building in real time with the help of a camera. This could provide more accurate readings far more quickly than current diagnostic tools allow.

As leaky buildings signal dwindling energy efficiency and higher utility bills to homeowners, auditors must be called in to figure out where those leaks are. Solving the problem means pinpointing exactly where air is escaping so that cracks can be sealed, but this process can be expensive, time-consuming, and cumbersome.

Traditionally, blower-door testing would be used to detect leaks in conjunction with smoke....]]> https://www.photonics.com/Articles/Oak_Ridge_Researchers_Use_Air-Leak_Detection/a69313 A69313 Tue, 12 Sep 2023 07:00:00 GMT

Superlenses made of plasmonic materials and metamaterials can image features at the subdiffraction scale. However, intrinsic losses restrict the image resolution of superlenses, hindering their widespread use.

To compensate for optical loss in superimaging systems, researchers at the University of Hong Kong (HKU) devised a way to provide virtual gain. To do so, they synthesized excitation waves of complex frequency, based on measurements at real frequencies. By illuminating materials with synthetic frequency waves, the researchers were able to implement virtual gain experimentally and retrieve subwavelength features. The multifrequency approach from HKU could provide a practical solution to overcoming the intrinsic losses of...]]> https://www.photonics.com/Articles/Complex_Frequency_Waves_Compensate_for_Optical/a69311 A69311 Mon, 11 Sep 2023 07:00:00 GMT

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.

Engineers at imec have integrated a pinned photodiode (PPD) structure in thin-film image sensors. According to the researchers, the addition of a pinned-photogate and a transfer gate into the thin-film image sensor architecture exploits the superior absorption qualities of thin-film imagers — beyond 1 µm.

Further, they said, the integration shows show that thin-film-based image sensors with a pinned photodiode structure can exhibit noise performance that is comparable to a silicon pinned photodiode pixel.

As a result, the advancement unlocks the potential of sensing light beyond the visible in a cost-efficient way.

Though the use of III-V materials can overcome this long-held detection range limitation, the...]]> https://www.photonics.com/Articles/Imec_Applies_Pinned_Photodiode_Structure_to/a69278 A69278 Mon, 28 Aug 2023 07:00:00 GMT
Raman spectroscopy is a useful tool for identifying microplastics — plastic particles smaller than 5 mm — although conventional point confocal Raman methods are limited to single-point detection, limiting the detection speed. A line-scan Raman spectroscopy method developed by the Chinese Academy of Sciences and Cardiff University significantly boosts detection speed for both micro- and nanoplastics.

The researchers reported a line-scan Raman microspectroscopy system capable of rapid imaging and chemical identification of microplastics down to 2000 nm in size, and capable of imaging a 40- × 10-µm particle in 10 s, representing a speed improvement by about two orders of magnitude compared to confocal imaging.
