The increased popularity of wearable electronic devices has led to a greater need for advanced sensors. However, fabricating pressure sensors that are flexible, highly sensitive, robust, and compatible with large-scale fabrication technology is challenging. This work investigates piezoresistive sensor constructed from an MXene/MoS2 hierarchical nanostructure, which obtained through easy inexpensive process. exhibits high sensitivity 0.42 kPa-1 (0-1.5 kPa), rapid response (∼36 ms), remarkable mechanical durability (∼10,000 cycles at 13 kPa). been demonstrated be successful in detecting human motion, speech recognition, physiological signals, particularly analyzing pulse. These data can used alert identify irregularities health. Additionally, the sensing units able construct arrays various sizes configurations, enabling distribution imaging variety application scenarios. research proposes cost-effective scalable approach arrays, utilized monitoring health use human-machine interfaces.
