“…The integration of NIRS with other neuroimaging technologies such as functional magnetic resonance imaging (fMRI) [69]- [71], EEG [72]- [74], positron emission tomography (PET) [75]- [77], and magnetoencephalography (MEG) [78]- [80], allows multimodal monitoring of physiological states and processes. The integration of NIRS and EEG, for example, facilitates the assessment of hemodynamic activity together with neurovascular coupling [55], [81], [82].…”

With a growing focus on properties of softness, miniaturization, and intelligence, extensive research has been focusing on constructing wearable electronic devices facilitating comfort, wearable health monitoring and diagnosis. Among recent progress in the development of wearable bioelectronics, wearable near-infrared spectroscopy (NIRS) devices demonstrate wide implementation possibilities in multiple health monitoring scenarios. Throughout the years, multiple design strategies have assisted in developing wearable NIRS devices with high wearing comfortability and miniaturized size. This review summarizes the principle of NIRS technology, recent advances in design strategies towards soft, wearable, miniaturized NIRS devices, and the future potential development directions. Based on the discussion of different design strategies, including modular device design, flexible hybrid electronics, and materials innovation, we also pinpoint some development directions for wearable NIRS. The reviewed and proposed research efforts may enhance the

“…Even though good clinical outcomes have been continuously reported, the accurate effect of tDCS on the brain has been not well established and still controversial [8], and thus investigation on brain state measured during tDCS is required to clarify the exact impact of tDCS on the brain. There are a variety of neuroimaging modalities to measure brain activity during tDCS, such as electroencephalography (EEG), magnetoencephalography (MEG) [9], near-infrared spectroscopy (NIRS) [10], functional magnetic resonance imaging (fMRI) [11], and so on.…”

BACKGROUND: Electroencephalography (EEG) measured during transcranial direct current stimulation (tDCS) can help understand the accurate impact of tDCS on the brain, but this has been hindered due to significant inflow of tDCS-induced electrical artifacts. OBJECTIVE: In this study, we introduce a novel tDCS device developed based on current limiter, which can prevent the generation of significant electrical artifacts. METHODS: To verify the feasibility of our developed tDCS device, we performed simultaneous measurement of EEG during tDCS application with five different current intensities (0, 500, 1,000, 1,500, and 2,000 µA). Changes in EEG power spectral density (PSD) and correlation between the PSD of non-stimulation and tDCS condition were investigated to see whether our tDCS device can be used for simultaneous EEG recording without significant inflow of tDCS-induced electrical artifacts. RESUTLS: The mean EEG-PSD differences between non-stimulation and tDCS condition were not significant for all stimulation current intensities. Furthermore, EEG-PSDs estimated during non-stimulation and tDCS application showed statistically high correlation for all comparison cases. CONCLUSION: Based on the results, we could demonstrate the feasibility of our tDCS device based on current limiter for simultaneous EEG measurement, which could potentially provide a way to investigate the impact of tDCS on the brain more accurately.
