Peelable Insulation Sheet Sensor for Wearable Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable sensors face challenges in minimizing size and preventing power consumption during non-use, as they require a switch device to manage power supply, which increases thickness and size.
Innovation Solution
The sensor design incorporates a base layer with conduction paths, adhesive layers, and an insulation sheet that acts as both a protective cover and a switch, allowing electrical connection only when the insulation sheet is peeled off, eliminating the need for a separate switch device and maintaining a compact size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a switch device is added to control power supply, then power consumption during non-use is avoided, but the size and thickness of the sensor increase
Solution Approach 1:
The patent combines the insulation sheet with the adhesive layer to create a single integrated component. The adhesive layer serves dual purposes: bonding the sensor to the skin and providing electrical insulation during non-use. This merging eliminates the need for a separate switch device, thereby preventing increase in sensor size and thickness while still avoiding power consumption during non-use.
Solution Approach 2:
The adhesive layer is designed to perform multiple functions simultaneously: it acts as both the bonding agent to attach the sensor to the subject's body and as the insulating element that prevents power consumption during non-use. This multi-functionality allows the sensor to avoid power consumption without requiring additional components that would increase its size.
2Loss of energy
If a switch device is added to control power supply, then power consumption during non-use is avoided, but the thickness of the sensor increases
Solution Approach 1:
The patent merges the insulation function with the adhesive layer, creating a single integrated component that serves both purposes. This combination eliminates the need for a separate switch device, thereby preventing increase in sensor thickness while still avoiding power consumption during non-use.

This multi-functionality allows the sensor to avoid power consumption without requiring additional components that would increase its thickness.
3Ease of operation
If the insulation sheet is made peelable, then the sensor can be easily activated and detached, but the structural complexity increases
Solution Approach 1:
The patent combines the insulation sheet and adhesive layer into a single integrated component with peelable properties. This merging allows the sensor to be easily activated by peeling off the adhesive layer, which simultaneously removes the insulation and activates the conduction path. The same peeling action also enables easy detachment, simplifying operation without adding structural complexity.
Solution Approach 2:
The adhesive layer is pre-configured with insulating properties and peelable characteristics before the sensor is used. This preliminary preparation allows the user to simply peel off the layer to activate the sensor, eliminating the need for separate activation mechanisms and reducing structural complexity.
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 configuration effectively prevents power consumption during non-use while maintaining a compact size, as the insulation sheet insulates the power source during non-use and connects it during use, ensuring efficient operation without the need for additional switch components.
Implementation Method 1
an insulation sheet including: a first protecting portion which is configured to peelably cover the second adhesive layer; a second protecting portion which is peelably disposed between a second portion of the first conduction path, and a part of the second conduction path
Implementation Method 2

AI summary
A sensor includes: a base layer; first and second conduction paths supported by the base layer; a first adhesive layer covering a first portion of the first conduction path; a second adhesive layer covering the second conduction path; an insulation sheet including: a first protecting portion covering the second adhesive laver; a second protecting portion disposed between a second portion of the first conduction path, and a part of the second conduction path; and a third protecting portion covering the first adhesive layer; a detecting section; a wireless transmitter; and a power source. When the insulation sheet is peeled off, the second portion of the first conduction path, and the part of the second conduction path are caused to be in contact with each other, and an electric power is supplied from the power source to the detecting section and the wireless transmitter.
