A catheter is introduced into the brain parenchyma during brain monitoring, an invasive method of checking the oxygenation of the brain tissue. As with any intrusive monitor, there is a chance of bleeding, infection, and equipment failure. In the intensive care unit, the degree of brain tissue oxygenation is a critical indicator. The estimated size of the global brain monitoring market, which was $5.78 billion in 2021, is expected to grow to $10.09 billion by 2030, reflecting a CAGR of 7.2 percent from 2021 to 2030. In critically ill or comatose patients, without a valid neurologic examination, it is difficult to assess the neurologic injury and the progression of severe neurologic impairment. Important medical decisions are based on the neurologic injury for common but severe diseases such the comatose condition following cardiac arrest, aneurysmal subarachnoid hemorrhage (aSAH), and severe traumatic brain injury (TBI). In the past, decisions on active intensive care management, the necessity for neurosurgical intervention, and the withdrawal of care have depended on scans like the electroencephalogram and intracranial pressure monitoring, which are both restricted estimates of the true state of brain impairment. Implantable & Wearable Sensory Systems for the purpose of Brain Monitoring Medical professionals and researchers can examine human behaviours, brain illnesses, and brain-computer interfaces thanks to brain monitoring tools (BCIs). By directly detecting the hemodynamic processes in the brain, the emerging field of study known as brain-computer interfaces (BCI) aims to improve human interaction and communication with the environment. Wearable imaging technologies, such as wearable photoacoustic tomography (wPAT) and magnetoencephalography (MEG), are widely used in research centres and medical facilities as portable standard brain imaging systems. A more detailed & complete picture of the various brain activities can be acquired by combining functional near-infrared spectroscopy (fNIRS), electroencephalogram (EEG), and other sensing methods. For accurate long-term brain monitoring, portability and implantation are necessary, particularly when the study calls for recording during routine everyday activities. Hot research areas in the pursuit of a high-resolution brain imager include implantable tiny complementary CMOS or the metal-oxide semiconductor image sensors & high-density probe arrays are integrated with the CMOS readout. A high-resolution implantable monitoring system faces various obstacles to overcome, including tissue heating brought on by the power used to operate the sensor and brain tissue injury during implantation. To generate high-quality brain activity monitoring and the diagnosis of neurological illnesses, signal processing procedures such as pre-processing, noise reduction, artifact rejection, source localization, connection, classification, and data visualization are crucial. The possibility of using wearable and implantable sensors for brain monitoring, as well as BCI technologies as a practical medical tool for next-generation brain monitoring, is demonstrated by the early detections of neurological disorders (like autism, epilepsy, & Alzheimer’s disease), as well as by real-time monitoring of cognitive loads and collaborative learning. To overcome the obstacles and accomplish this goal, innovations in signal processing and at the system, circuit, and device levels are needed. In recent years, a number of implantable and portable brain monitoring technologies and methods have been investigated. The goal of this special issue is to raise awareness of this rapidly developing area and encourage additional research into high-resolution portable and implantable sensors for brain monitoring. CONCLUSION The market for brain monitoring systems is anticipated to reach a significant milestone in the future with an exponential growth rate due to the aforementioned considerations. Newer and improved brain monitoring technologies will become available as time goes on, assisting the global market’s expansion. Also read- Multiplex Assays Market :
