Implant Sensor Network Temperature Management via Node Clustering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional implantable body sensor networks do not have a method to continuously maintain the operation of implant sensor nodes when their temperature exceeds a threshold, potentially harming the patient, as they focus solely on routing biomedical signals without addressing the issue of temperature control for the sensor nodes themselves.
Innovation Solution
The network divides sensor nodes into clusters with roles assigned as active, relay, and substitute nodes, allowing the control device to manage operations, stopping the active node and starting the substitute node when the active node's temperature exceeds the threshold, ensuring continuous monitoring without harm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the implant sensor node continuously operates to monitor biomedical signals, then the monitoring function is maintained, but the temperature of the sensor node increases to a level that may harm the human body
Solution Approach 1:
The patent segments the sensor network into multiple clusters, each with active and substitute nodes. This segmentation allows the system to distribute the monitoring function across multiple nodes, enabling seamless transition when temperature becomes harmful, thus maintaining reliability while preventing damage.
Solution Approach 2:
The patent implements preliminary action by pre-configuring substitute nodes and establishing transition protocols before temperature becomes harmful. When the active node's temperature reaches a threshold, the system can immediately switch to the substitute node without interruption to monitoring, preventing harm while maintaining continuous operation.
2Object-affected harmful factors
If the active node stops operation when temperature exceeds threshold, then temperature-related harm is prevented, but the monitoring function is interrupted
Solution Approach 1:
The system performs preliminary action by pre-configuring substitute nodes and establishing transition protocols before the active node needs to stop. When temperature exceeds the threshold, the substitute node is already prepared to take over immediately, preventing both harm and interruption of the monitoring function.
Solution Approach 2:
The patent ensures continuity of useful action through the substitute node mechanism. When the active node stops due to temperature, the substitute node immediately continues the monitoring function, ensuring that the useful action of biomedical signal monitoring continues without interruption while the active node cools down.
3Reliability
If the substitute node takes over when active node temperature is high, then continuous monitoring is maintained, but additional control complexity is introduced
Solution Approach 1:
The patent segments the network into clusters with clearly defined active and substitute nodes. This segmentation simplifies the control complexity by creating a straightforward hierarchical structure where each node has a specific role, making the takeover process manageable and systematic rather than requiring complex global coordination.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach ensures safe and continuous monitoring of biomedical signals by allowing the substitute node to take over when the active node's temperature exceeds the threshold, preventing damage to the patient and maintaining the operation of the implantable body sensor network.
Implementation Method 1
When the sensor node implanted in the human body (hereinafter, referred to as 'implant sensor node') in the human body sensor network monitors biomedical signals or transmits the monitored biomedical signals to the cellular phone or the small-scale base station, it generates heat.

AI summary
The present invention relates to a sensor network, and more particularly, to an implanted sensor network in a human body sensor network in which a plurality of sensor nodes are implanted in the human body to detect biosignals of the human body, wherein the implanted sensor network can prevent the temperature of a sensor node implanted in a human body from rising and thus protect the human body from injury caused thereby.
