Capillary Drying Pathway for Sensor Transducers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transducers in electronic devices, such as sensors, take a long time to dry after exposure to humidity and water due to slow water removal, which can affect their operation.
Innovation Solution

Engineering Contradiction Analysis
1Reliability
If transducers are exposed to humidity and water, then they can perform sensing functions, but they take a long time to dry which affects their operation
Solution Approach 1:
A capillary-dense material is introduced as an intermediary substance between the transducer and the external environment. This material creates capillary channels that actively transport water away from the transducer through capillary pressure gradients, significantly accelerating the drying process without requiring external energy input or active control systems.
Solution Approach 2:
The patent employs a capillary-dense material with a porous structure that provides numerous capillary channels. These pores create capillary forces that draw water away from the transducer surface through the porous material, enabling rapid passive drying while maintaining structural integrity and sensing functionality.
2Productivity
If capillary-dense material is added to the tubular structure, then drying efficiency is improved, but device complexity increases
Solution Approach 1:
The capillary-dense material is integrated directly into the tubular structure, utilizing its porous nature to create drying channels. This approach improves drying efficiency while avoiding the need for separate active drying components, motors, or control systems, thereby limiting the increase in overall device complexity.
Solution Approach 2:
The capillary-dense material creates a self-regulating drying system that operates passively through capillary pressure gradients. The structure automatically draws water away from the transducer without requiring external power sources, control mechanisms, or complex active management systems, thus improving productivity with minimal complexity addition.
