Harnessing the interfacial polarisation phenomenon offers a transformative pathway for developing highly sensitive and flexible piezocapacitive soft sensors tailored for advanced human motion monitoring. This project sets out to push the boundaries of wearable sensing technologies by engineering a new class of nanomaterial-doped, lattice-based soft piezocapacitive sensors (NDLSPCS). These next-generation materials are designed to respond with exceptional precision to even subtle mechanical deformations, enabling real-time detection of motion with significantly enhanced accuracy, stability and durability.

At the core of the initiative is the strategic use of interfacial polarisation within nanocomposite structures. By embedding functional nanomaterials into engineered lattice frameworks, the project seeks to amplify piezocapacitive responses far beyond what conventional soft sensors can achieve. This approach not only enhances sensitivity but also ensures flexibility and mechanical robustness—two essential characteristics for wearable applications that must conform seamlessly to the human body.

Ultimately, the work aims to demonstrate a sensor platform that integrates scientific innovation with real-world applicability, paving the way for a new generation of wearable systems that monitor motion with unprecedented fidelity and user comfort.
