“…Several wearable devices for blood flow monitoring have been developed based on electrical ( Etemadi et al., 2015 ; Rosa et al, 2019 ; Cluff et al., 2017 ), mechanical ( Etemadi et al., 2015 ; Wiens et al., 2014 ), acoustic ( Rosa et al, 2019 ; Kenny 2021 ; Kenny et al., 2020 ), and optical ( Abtahi et al. 2016 ; Saikia and Mankodiya 2018 ) approaches. In particular, photothermal method-based measurement of temperature gradients due to light-induced heating holds promise for integration into a lightweight wearable device, but currently relies on optically opaque thermal sensors that hinder accurate measurement.…”

“…Clinical validation studies will be required to establish the performance of the wearable optoelectronic device compared with the gold standard, such as Doppler ultrasound for blood flow monitoring ( Kenny 2021 ; Kenny et al., 2020 ). Additional modalities, such as impedance cardiography ( Cluff et al., 2017 ) and reflectometry ( Saikia and Mankodiya 2018 ), can also be incorporated to improve sensing accuracy.…”

Summary Wearable optoelectronic devices can interface with the skin for applications in continuous health monitoring and light-based therapy. Measurement of the thermal effect of light on skin is often critical to track physiological parameters and control light delivery. However, accurate measurement of light-induced thermal effects is challenging because conventional sensors cannot be placed on the skin without obstructing light delivery. Here, we report a wearable optoelectronic patch integrated with a transparent nanowire sensor that provides light delivery and thermal monitoring at the same location. We achieve fabrication of a transparent silver nanowire network with >92% optical transmission that provides thermoresistive sensing of skin temperature. By integrating the sensor in a wireless optoelectronic patch, we demonstrate closed-loop regulation of light delivery as well as thermal characterization of blood flow. This light delivery and thermal monitoring approach may open opportunities for wearable devices in light-based diagnostics and therapies.

Near-infrared spectroscopy (NIRS) has become a key modality in medical imaging, finding application in both brain and breast imaging. This paper discusses the current trends in NIRS for brain and breast imaging, exploring advances in multi-modal integration with modalities such as functional magnetic resonance imaging (fMRI) and electroencephalography (EEG). Challenges related to spatial resolution, depth sensitivity, and the impact of extracerebral tissues on signal specificity are examined. In addition, ongoing efforts to enhance hemodynamic measurements’ quantitative accuracy. Challenges, including limited spatial resolution and tissue heterogeneity, are discussed. The discussion extends to diffuse optical tomography and ongoing instrumentation development, clinical trials and studies validating NIRS diagnostic efficacy in breast imaging. The paper emphasizes the need for standardization, integration into routine clinical practice, and motivates for future work.

Breast cancer is a global health concern, necessitating continuous advancements in diagnostic medical imaging technologies for early detection and improvement of treatment. This paper presents an overview of the past, present and future of breast cancer imaging using light and some results from the current studies. The paper specifically presents the role of Diffuse Optical Tomography (DOT) in breast cancer imaging. Conventional methods, such as X-ray mammography, face limitations. Diffuse Optical Tomography, a non-invasive light-based imaging modality can provide quantitative descriptive and architectural information about breast tissue. The paper discusses the key challenges and recent developments in breast cancer imaging using DOT to overcome some key challenges. This paper aims to contribute to the understanding of the evolving technological landscape in breast cancer imaging using light for improving early detection and patient outcomes.
