1. Micro/nano fabrication and intelligent integration of flexible electronics

Nano/microfabrication and intelligent integration are pivotal pathways to developing high-performance flexible electronics. In this study, we developed an in-situ forming method for porous conductive copolymers, constructing conformally attachable mechanical sensors, integration with intelligent algorithms, enabling the recognition of faint signals such as pulse and sound. Furthermore, a gravity-driven sedimentation process was proposed, yielding conductive hydrogels with stretchability up to 1100%, along with an all-in-one fabrication strategy of hydrogel electronics that facilitates multi‑dimensional integrated manufacturing of hydrogel‑based electronic devices.

2. Bioinspired flexible bio-integrated electronics for personized healthcare

Cardiovascular disease (CVD) remains the leading cause of mortality worldwide. Hemodynamic monitoring plays a crucial role in its prevention and postoperative management. However, current clinical hemodynamic monitoring equipment is often costly, bulky, and limited to intermittent monitoring. Flexible flow sensors offer a promising solution for real-time and continuous hemodynamic monitoring. We have developed two types of flexible sensors—wearable and implantable—for hemodynamic assessment, achieving clinical-grade monitoring accuracy and enabling diagnosis of related conditions.

心血管疾病（CVD）仍是全球范围内的首要致死病因。血流动力学监测在其疾病预防与术后管理中发挥着关键作用。然而，现有临床血流动力学监测设备普遍存在成本高昂、体积庞大，且仅能实现间歇性监测等局限。柔性流动感知器件为实时、连续的血流动力学监测提供了极具前景的解决方案。研制了可穿戴式与植入式两类用于血流动力学评估的柔性传感器，均达到临床级监测精度，可实现相关病症的初步诊断。

3. Bioinspired hydrodynamic sensing E-skins for underwater exploration

Flow sensing equips underwater robots with a "hydrodynamic imaging" capability, enabling them to operate in turbid environments. Commercial pressure sensors, however, suffer from rigidity and limited performance, making them difficult to integrate onto complex curved surfaces and achieve high-precision detection. We revealed the sensitivity-enhancing mechanism of flow-sensing units in eyeless cavefish lateral lines induced by constriction structures, and constructed an artificial canal lateral line system with constriction structures, achieving a detection limit of 3.2 mPa, comparable to that of the biological prototype. Furthermore, we elucidated the sensitivity-enhancing mechanism of the flow-sensing array induced by a unique head-horn body shape, and developed an artificial lateral line array employing a dual-stagnation-point sensitization strategy, leading to a 95% accuracy rate in underwater obstacle recognition.
