Wireless brain sensors track temperature, detect intracranial pressure, and record brain transmission in the form of brain waves.
Sleep disorders, traumatic brain injury, dementia, Parkinson’s disease, and other neurological illnesses are some of the major ailments for which brain sensors are most commonly utilized.
Wireless connection allows brain sensors to be accessed remotely. These sensors can be linked with smartphones, tablets, and laptops. As a result, they may be monitored intermittently from a homecare environment, making the device cost-efficient.
Earlier, sensors tied people to the monitoring site and necessitated their removal when the patient recovered. Later, clinical-grade wireless brain sensors were developed, which combined bio-friendly metals (magnesium, zinc, and titanium) that worked as conductive elements.

What is Neurotransmission?
In neurotransmission process, a signal molecule binds to a specific binding site, activates another target molecule downstream of the receptor, and continues to activate more target molecules and proteins until the desired signal is created. This created signal then travels up the spine and to the brain, where neurons are situated.
A brain has 100 billion neurons, which are nerve cells that allow one to respond to various impulses.
A neuron is made up of a nucleus, an axon, dendrites, a myelin sheath, and an axon terminal.
A signal is sent to a neuron in the form of an electrical impulse known as “action potential,” which travels from the neuron’s dendrites to the axon terminal.
The action potential stimulates the nerve cell to release neurotransmitters (signaling molecules), which attach to the receptor on the next neuron.
The synapse is the location between the two neurons where the neurotransmission is taking place. If the released electrical charge on these neurotransmitters into the synapse is greater than the threshold, an action potential will be formed; otherwise, nothing will happen, and the signal transduction will be terminated. These are referred to as excitatory and inhibitory states, respectively.
When a group of neurons experiences a shift in electrical impulse, it creates an electrical field that looks like vibration and may be recorded on the scalp by electroencephalogram (EEG) sensors.
In a nutshell, the brain receives an electrical signal, which causes an action potential to occur within neurons.
The action potential travels across neurons through a synapse, generating an electrical field observed by scalp sensors.
Factors that Influence the Use of Wireless Brain Sensors
Wireless brain sensors are primarily driven by the following variables:
- Investment in research and development: Factors such as changing social environments, more research funding, technological advancements, increased awareness of neurological issues, and the rising occurrence of dementia are expected to drive demand for wireless brain sensors. Additionally, massive technological advancements in the field of brain-computer interfaces have resulted in the continuous enhancement of brain sensors.
- Unhealthy lifestyle choices: One of the key factors driving the utilization of wireless brain sensors is the increase in unhealthy lifestyles adoption among the masses.
Unhealthy lifestyle choices, such as alcohol addiction and smoking, are major contributors to ailments such as stroke and migraine.
Every year, around 70,000 people in the U.S. suffer from strokes, with the majority of strokes being fatal or resulting in long-term impairment. Furthermore, smoking is a substantial risk factor for hemorrhagic and ischemic stroke.
According to several credible sources, some of the lifestyle variables that influence health are exercise, nutrition, weight management, rest, and many more.
- Increased number of traumatic brain injuries: Traumatic brain injuries (TBI) have become more common in the twenty-first century, and this is one of the major causes driving demand for wireless brain sensors.
TBIs caused by a bump, blow, or shock to the head result in irreversible brain damage. Sports-related injuries such as falls, gunshot injuries, domestic violence, and car accidents are common causes of TBIs.
TBI is a leading cause of morbidity and mortality across the world. In the future, the demand for wireless brain sensors will be boosted by the rising geriatric population and surging technological advancements.
To conclude, wireless brain sensors can be used to monitor patients with traumatic brain injuries and other neurological disorders.
The market for wireless brain sensors is expected to grow significantly due to factors such as an increasing geriatric population, an increase in the prevalence of neurological disorders and traumatic brain injuries, an increase in stress levels, and increased penetration of smartphones and the internet.
