Solution Overview
Problem
Existing probes used for electrical stimulation in the brain often cause side effects due to inaccurate control over the scope of electrical stimulation, necessitating the development of a probe that minimizes these side effects.
Innovation Solution
A physiological sensing and/or stimulation probe with a movable second electrode, adjustable via an adjusting unit, allowing the angle of the electrical field generated between the first and second electrodes to be adjusted, thereby controlling the direction and scope of electrical stimulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed electrode configuration is used, then the probe structure is simple, but the electrical stimulation scope cannot be accurately controlled causing side effects
Solution Approach 1:
The patent applies the dynamics principle by making the second electrode movable relative to the first electrode through an adjusting unit. This allows the angle between the electrodes to be dynamically adjusted, enabling precise control over the electrical stimulation scope while maintaining a relatively simple overall probe structure. The movable configuration transforms a static electrode arrangement into a dynamic one, resolving the contradiction between precision and complexity.
2Object-affected harmful factors
If the electrical field angle is fixed, then the probe is easy to manufacture, but side effects occur due to inaccurate stimulation scope control
Solution Approach 1:
The patent applies segmentation by dividing the electrode system into two separate electrodes (first electrode and second electrode) that can be independently positioned and adjusted. This segmentation allows for precise control of the electrical field angle and stimulation scope, reducing side effects while maintaining manufacturing feasibility through modular assembly of the adjusting unit.
3Reliability
If an adjustable electrode angle is implemented, then side effects are reduced through precise control, but the adjusting unit increases device complexity
Solution Approach 1:
The patent applies parameter changes by enabling adjustment of the angle parameter between the two electrodes through the adjusting unit. This parameter adjustment mechanism allows precise control of the electrical field orientation, improving stimulation accuracy and reducing side effects. The adjusting unit implements this parameter change capability with a design that balances functionality and complexity.

AI summary
A physiological sensing and/or stimulation probe and method. The physiological sensing and/or stimulation probe includes a probe body, a first electrode, a second electrode and an adjusting unit. The first electrode is disposed on the probe body. The second electrode is spaced apart from the first electrode and has an outer surface facing away from the first electrode. The second electrode is movably disposed on the probe body via the adjusting unit so that an angle between a normal direction of the outer surface of the second electrode and a central line of the probe body is adjustable, thereby allowing an electrical field generated between the first electrode and the second electrode to be adjustable.
