Solution Overview

Problem

High integration density in sensor matrices leads to crosstalk issues due to densely packed supply and readout electrodes, causing signal interference and blurring of captured images, especially in high-resolution applications with large signal level differences.

Innovation Solution

The second electrode arrangement is positioned on a top layer over the carrier layer, allowing for an electrically conductive contact with the component arrangement, reducing crosstalk and enabling more space for electrode placement, while allowing for separate manufacturing of the carrier and top layers, and potential elasticity for application on uneven surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If supply and readout electrodes are densely packed on the carrier layer to achieve high integration density, then component density is improved, but signal interference and crosstalk increase

Engineering Contradiction:
Improvecomponent densityVSAvoidsignal interference and crosstalk
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent transitions from a planar electrode arrangement to a three-dimensional configuration by placing the readout electrode on the top layer above the carrier layer. This vertical separation in the third dimension allows high component density on the carrier layer while maintaining sufficient distance between supply and readout electrodes to prevent crosstalk and signal interference.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The device is divided into two separate layers: the carrier layer containing the component arrangement and supply electrodes, and the top layer containing the readout electrode. This segmentation allows each layer to be optimized independently for its specific function while reducing electromagnetic interference between electrodes.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If electrodes are arranged in a grid pattern to access individual components, then component accessibility is improved, but electrode density and crosstalk risk increase

Engineering Contradiction:
Improvecomponent accessibilityVSAvoidcrosstalk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Instead of increasing electrode density in the planar grid to access individual components, the patent uses the vertical dimension by placing the readout electrode on the top layer. This allows selective access to components through vertical positioning without increasing horizontal electrode density, thereby maintaining low crosstalk while preserving component accessibility.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of manufacture

If carrier layer and top layer are manufactured separately, then manufacturing flexibility and cost are improved, but assembly complexity increases

Engineering Contradiction:
Improvemanufacturing flexibilityVSAvoidassembly complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The device is designed as separable layers that can be manufactured independently using different processes and materials optimized for each function. The carrier layer can be produced with flexible substrates and low-temperature processing, while the top layer can be manufactured separately and then bonded to the carrier layer through simple lamination or adhesive bonding, minimizing assembly complexity despite manufacturing separation.

Inventive Principle:
Principle #1Segmentation
