Dataset for the paper, "Fast and Precise Tongue Pressure Measurement by Intraoral Laser-Induced Graphene Pressure Sensor for Elderly Healthcare".

Tongue pressure (TP) monitoring is essential for evaluating oral functions and improving elderly healthcare, particularly in addressing challenges related to chewing, swallowing, and speech. However, commercial balloon-based TP sensors have limitations in large footprints, small linear response ranges, and practical challenges in durability and replacement. Here, we introduce a novel TP sensor based on laser-induced graphene (LIG), fabricated through direct laser writing. This sensor is designed to provide a smaller footprint, higher linearity, enhanced durability, and simpler maintenance for advanced elderly healthcare. LIG patterns were generated on polyimide films by direct irradiation of ultraviolet (UV) nanosecond laser pulses and transferred onto biocompatible polydimethylsiloxane (PDMS) substrates. The sensor was encapsulated with an additional thin layer of PDMS to protect the oral environment. The fabricated TP sensor demonstrated exceptional sensitivity of 0.00594 kPa-1 across a wide pressure range (1 to 300 kPa), with rapid response times and long-term cyclic robustness. In-vivo tests validated its reliable and precise TP monitoring capability, proving its effectiveness in practical uses. Our approach paves a way for 3D-printed smart dentures for advanced elderly care while also offering broader applications in oral rehabilitation and biomechanical human-aid devices for general body pressure sensing.舌压力（Tongue Pressure, TP）监测对于评估口腔功能、改善老年医疗保健至关重要，尤其在解决咀嚼、吞咽与言语相关的临床挑战方面意义重大。然而，基于气囊的商用TP传感器存在占位面积过大、线性响应范围狭窄的缺陷，且在耐用性与更换维护方面面临实际应用难题。在此，我们提出一种基于激光诱导石墨烯（Laser-Induced Graphene, LIG）的新型TP传感器，通过直接激光写入工艺制备而成。该传感器旨在实现更小的占位面积、更高的线性度、更强的耐用性以及更简便的维护，以服务于先进的老年医疗保健场景。研究团队通过紫外（Ultraviolet, UV）纳秒激光脉冲直接辐照，在聚酰亚胺薄膜上制备得到LIG图案，并将其转移至生物相容性的聚二甲基硅氧烷（Polydimethylsiloxane, PDMS）基底上。随后通过额外添加一层薄PDMS对传感器进行封装，使其适配口腔环境。所制备的TP传感器在1~300 kPa的宽压力区间内展现出0.00594 kPa⁻¹的优异灵敏度，同时具备快速响应特性与长期循环鲁棒性。体内实验验证了其可靠且精准的TP监测能力，证实了该传感器具备实际应用价值。本研究方案为面向高级老年照护的3D打印智能义齿开辟了新路径，同时也为口腔康复以及用于全身压力传感的生物力学人体辅助装置等领域提供了更广阔的应用前景。
