Background:

• Accurate pressure application is crucial for hemostasis after transradial procedures.
• Current subjective pressure assessment can lead to inadequate hemostasis or thrombosis.
• Objective monitoring is needed to optimize pressure management and patient safety.

Purpose of the Study:

• To develop a compact, wireless sensing system for continuous pressure monitoring during transradial procedures.
• To enable real-time data transmission for informed clinical decision-making.
• To improve the quality and safety of transradial interventions.

Main Methods:

• Fabrication of a liquid metal (LM)-based, all-soft pressure sensor for conformal skin attachment.
• Integration of wireless technology for real-time data transmission to mobile devices.
• Testing sensor sensitivity and performance across a wide pressure range (0-100 kPa).

Main Results:

• Achieved linear sensitivity of 0.007 kPa⁻¹ over a 0-100 kPa pressure range.
• Demonstrated real-time wireless data transmission of applied pressure.
• Developed a system for continuous, objective pressure monitoring.

Conclusions:

• The developed wireless sensing system offers a reliable method for objective pressure monitoring in transradial procedures.
• Continuous data collection and analysis can enhance surgical quality and reduce postoperative complications.
• This technology provides a valuable tool for medical assistance and improving patient care.
