Decoupled and high-sensitivity strain–temperature bimodal sensors based on chitosan-enhanced hydrogel with local strain concentration

Key Points

• These bimodal sensors demonstrate high sensitivity to both strain and temperature changes, making them useful for various applications.
• Placing the sensors in a chitosan-enhanced hydrogel matrix increases local strain concentration significantly, improving performance.
• Using this hydrogel allows for more effective strain and temperature detection, which is critical in many scientific fields.
• The findings highlight potential benefits for high-precision monitoring, though further real-world applications may be needed.
