Flexible Biometric Sensor Mount with Segmented Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biometric monitoring systems face challenges in comfortably and effectively integrating sensors and electronics onto the human body for continuous, accurate measurement of biometric signals, particularly in areas requiring skin contact, while minimizing bulk and ensuring reliable data transmission.
Innovation Solution
A sensor mount system that incorporates flexible straps and substrates with integrated conductive materials and electronics, allowing sensors to be positioned directly on the skin while the electronics unit is external, with wireless communication capabilities and a modular design for secure attachment to clothing or accessories, using conductive textiles and polymers for seamless data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If sensors and electronics are integrated into a single unit for biometric monitoring, then data transmission and processing are simplified, but the bulk and discomfort to the wearer increases
Solution Approach 1:
The monitoring system is divided into separate components: sensors that contact the skin are separated from the electronics unit that processes data. This segmentation allows the lightweight sensor portion to be worn directly on the body while the electronics can be positioned externally or in a separate compartment, reducing the bulk at the sensor location and improving comfort.
2Measurement precision
If sensors are placed directly on the skin for accurate biometric measurement, then measurement precision is improved, but comfort and ease of wear deteriorates due to bulk and potential irritation
Solution Approach 1:
The electronics unit is extracted from the sensor assembly, allowing the sensors to be minimized to only the essential contact elements needed for accurate measurement. This extraction reduces the bulk and potential irritation sources while maintaining direct skin contact for precision, as the larger electronics component can be positioned elsewhere.
3Ease of operation
If a modular design with external electronics is used, then comfort and flexibility are improved, but device complexity and attachment security worsen
Solution Approach 1:
The modular attachment system is designed with universal features that allow the sensor mount to be securely attached to various types of clothing and accessories (straps, belts, garments). This multi-functional attachment capability simplifies the overall system by using a single modular interface for different application scenarios, reducing the complexity of designing separate attachment mechanisms for each use case.

AI summary
A sensor mount may include a flexible substrate that may be folded to form a flexible inner portion that may be arranged to face a wearer and a flexible outer portion that may be arranged to face away from the wearer. The flexible inner portion and the flexible outer portion may define a channel and may be configured to secure the sensor mount to an article of clothing. A belt may be connected to the flexible outer portion. The outer flexible portion may include two slits configured to receive the belt such that the belt may be attachable to the outer flexible portion of the flexible substrate. A sensor may be disposed on the flexible inner portion of the flexible substrate.
