Wearable EEG System with 360-Degree Camera for Ambulatory Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing EEG devices are bulky, inflexible, and restrict patient mobility due to rigid structures and multiple long wires, and they primarily detect motor activity and generalized tonic-clonic seizures, failing to capture ambulatory EEG with clear visibility of the surroundings, which is essential for diagnosing epilepsy triggers in everyday settings.
Innovation Solution
A wearable system with EEG sensors and a minimally obstructive 360-degree image capturing unit that allows patients to move freely while recording EEG signals and their environment, transmitting data remotely for real-time evaluation by clinicians, ensuring full visibility of the patient's face and arms, and capable of being used during daily activities, including sleeping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional rigid structures and multiple long wires are used in EEG devices, then structural stability is maintained, but patient mobility is restricted and device flexibility is reduced
Solution Approach 1:
The EEG device is divided into separate modular components: a wearable headgear unit with EEG sensors, a separate processing unit, and a camera system. This segmentation allows each component to be optimized independently, improving flexibility while maintaining functionality.
Solution Approach 2:
The device transitions from rigid conventional structures to dynamic, adaptable components including flexible headgear that can accommodate head movements, wireless communication that eliminates physical wire constraints, and adjustable positioning systems that adapt to patient needs during mobility.
2Loss of information
If existing EEG devices are used to detect motor activity and generalized tonic-clonic seizures, then detection capability is provided, but diagnostic completeness is insufficient for epilepsy triggers in everyday settings
Solution Approach 1:
The EEG device is enhanced with multi-functionality by integrating camera systems for video recording, environmental sensors for trigger detection, and processing capabilities for various seizure types. This universal design enables the device to detect not only motor activity but also environmental triggers and subtle seizure manifestations, providing comprehensive diagnostic information for epilepsy evaluation in everyday settings.
3Loss of information
If video camera is used to acquire ambulatory EEG, then visual monitoring is provided, but patient mobility is limited and surrounding environment visibility is lost
Solution Approach 1:
The camera system is positioned and oriented to capture environmental information from multiple dimensions and perspectives. The system records video in the direction the patient is facing while simultaneously capturing surrounding environment data, adding spatial dimensionality to the monitoring and preserving both patient mobility and environmental context visibility.
Data Source
AI summary
A system and method of capturing electroencephalograms (EEG) in real-time are disclosed. The system includes an EEG controller. A user wears or puts on the carrier. The carrier includes a casing for receiving the EEG controller, and includes a plate for connecting an image capturing unit. The EEG controller connects to cables having EEG sensors placed over the head of the user. The EEG sensors collect EEG signals and send them to the EEG controller via the cables. The image capturing unit captures images or video surrounding the user. The EEG controller captures data from the EEG sensors and the image capturing unit to monitor and evaluate the clinical status of the user.
