该论文提出了一种基于时分扩频码的多通道fNIRS集成电路，用于便携式功能性脑成像，解决了现有脑监测技术（如CT和MRI）昂贵且不便携的问题，实现了15pW可检测灵敏度。
degenerative brain diseases, such as stroke and Alzheimer’s disease, is rapidly increasing. It is imperative for those suffering from such slow progressing and recurring brain diseases to continuously monitor and manage their brain conditions. Currently available brain-monitoring techniques, such as computed tomography (CT) and magnetic resonance imaging (MRI) are expensive and cumbersome for such a purpose, resulting in the need to develop a brain monitoring system in the form of a wearable healthcare device. When the brain is activated, neurons are supplied with oxygen, and the oxyhemoglobin (HbO2) and deoxyhemoglobin (HbR) concentrations in the blood of surroundings of the neurons vary. These variations are called hemodynamics. Based on the principle that absorption coefficients of HbO2 and
