Solution Overview
Problem
Current systems fail to quantitatively detect and track the progression of neurological diseases and the efficacy of treatments, as they do not consider the initial state of neuronal-brain regions or interplay, leading to incomplete conclusions and inadequate diagnosis and management of neurological disorders.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional systems are used to record neuronal data, then data collection is simple, but the systems cannot quantitatively detect and track the progression of neurological diseases or treatment efficacy
Solution Approach 1:
The BCP implements a closed-loop feedback system that continuously monitors neuronal activity, compares it against baseline data, and adjusts treatment parameters in real-time. This enables quantitative tracking of disease progression and treatment efficacy by measuring changes in neuronal signals over time and using this information to modulate stimulation parameters dynamically.
Solution Approach 2:
The BCP acts as an intermediary device between the neuronal tissue and external control systems. It receives raw neuronal signals, processes them through onboard computing resources, and translates them into actionable insights for disease tracking and treatment adjustment, bridging the gap between simple recording and complex analysis.
2Speed
If the BCP device is implanted for direct neuronal interaction, then real-time bidirectional communication is achieved, but surgical intervention and implantation risks increase
Solution Approach 1:
The BCP replaces mechanical/electrical recording methods with optical detection using voltage-sensitive dyes and fluorescence imaging. This substitution enables real-time monitoring of neuronal membrane potential changes without requiring invasive electrode implantation, thereby achieving high-speed communication while reducing surgical risks and tissue damage.
Solution Approach 2:
The system uses optical fields as an intermediary to detect and communicate with neuronal tissue. Instead of direct electrical contact that requires surgery, the BCP uses light to probe neuronal activity and deliver optical stimulation, creating a non-invasive interface between the device and the nervous system.
3Manufacturing precision
If advanced nanotechnology and optogenetics are used for precise neuronal modulation, then treatment precision is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The BCP achieves precise neuronal modulation by dynamically adjusting multiple parameters including optical wavelength, fluorescence excitation intensity, and stimulation timing. These parameter changes enable fine-tuned control of neuronal activity without requiring complex nanoscale device structures, simplifying manufacturing while maintaining high precision.
Solution Approach 2:
The system replaces complex mechanical nanoscale structures with optical and chemical mechanisms. Instead of using nanoscale electrodes or mechanical actuators that are difficult to manufacture, the BCP uses voltage-sensitive dyes, optical fields, and fluorescence imaging to achieve precise neuronal modulation with simpler, more manufacturable components.
4Measurement precision
If continuous monitoring and closed-loop control are implemented, then disease tracking accuracy is improved, but energy consumption increases
Solution Approach 1:
The BCP implements periodic monitoring cycles rather than continuous operation. It alternates between measurement phases where fluorescence signals are captured and analysis phases where data is processed and treatment parameters are adjusted. This periodic operation maintains high tracking accuracy while reducing average power consumption by keeping the system in low-power states between measurement cycles.
Solution Approach 2:
The system maintains continuous useful action through efficient use of the fluorescence signal. Once excitation is applied, the BCP captures the entire fluorescence decay curve continuously, extracting maximum information from each excitation event. This eliminates the need for repeated excitations and reduces overall energy consumption while maintaining continuous monitoring capability.
