Large-area electronic sensor and actuator arrays are suitable systems for thin-film transistor (TFT) technology with numerous applications from consumer electronics to healthcare. Considerable effort is being spent to make these arrays a reality. However, research on the power delivery circuits that supply these arrays has remained largely unexplored. This work delves into the design trade-offs and characterization of high output power boost converters in low-temperature polysilicon (LTPS) technology. The proposed boost converters deliver 0.62–2.17 W of output power, orders of magnitude above prior TFT solutions, with efficiencies ranging from 47 to 69.5%. These boost converters enable the realization of large-area sensor and actuator arrays and set the foundation for future research in this area.

Retinal degeneration, marked by the progressive loss of photoreceptors, is a leading cause of blindness. Photocapacitive biointerfaces provide a prosthesis-style approach to reestablish light-driven neural activity. Here, we present a flexible Cu₂SnS₃ quantum dots/polymer heterojunction (P3HT:PCBM)-based hybrid biointerface that enables wireless photoelectrical stimulation of neurons. The device is forming a stack whose effective capacitance and photocurrent scale with wavelength, emulating retinal spectral sensitivity. When interfaced with neurons, the heterojunction produces red-light-evoked photocurrents (peak ~4.5 nA at 8 mW cm⁻²) and drives measurable changes in both membrane potential and intracellular calcium (ΔF/F₀ increase of ~10%). The operation is non-thermal and remains in the capacitive regime, while the hybrid architecture enhances charge separation and interfacial storage compared with single-material layers. These results define a flexible photocapacitive platform that achieves visible/NIR neuromodulation. Validation on hippocampal neurons and future studies on retinal ganglion cells advance this platform toward prosthetic vision applications.
视网膜变性以光感受器的逐渐丧失为特征，是导致失明的主要原因。光电容性生物界面提供了一种假体式的方法来重建光驱动的神经活动。在这里，我们提出了一种基于柔性Cu₂SnS₃量子点/聚合物异质结（P3HT:PCBM）的混合生物界面，可以实现神经元的无线光电刺激。该装置模拟视网膜光谱灵敏度，形成有效电容和光电流随波长变化的堆叠。当与神经元连接时，异质结产生红光诱发光电流（8 mW cm - 2时峰值~4.5 nA），并驱动膜电位和细胞内钙的可测量变化（ΔF/F 0增加~10%）。与单一材料层相比，混合结构增强了电荷分离和界面存储。这些结果定义了实现可见/近红外神经调节的柔性光电容平台。海马体神经元的验证和视网膜神经节细胞的未来研究将推动该平台向假肢视觉应用。

Flexible millimeter-wave (mmWave) antennas hold great promise for conformal integration across diverse devices and high-speed, large-channel capacity in 5G/6G wireless communications. Spoof surface plasmon polaritons (SSPPs) structure with periodic grooves is well-suitable for designing miniaturized, flexible and ultra-wideband planar mmWave antennas. However, achieving high-precision fabrication of SSPP configurations with optimal micrometer-scale filling factors using flexible conductive materials remains highly challenging. Herein, we report the high-precision all-Ti3C2-printed flexible ultra-wideband mmWave endfire antennas based on SSPPs for wireless communication. The SSPPs antenna exhibits a wide operating bandwidth of 25–49 GHz, which stems from the reactance properties of the ordered multilayer structure of Ti3C2. The S-parameter and gain can be well maintained even after cyclic bending, owing to the robust adhesion between the polydopamine-modified substrate and the Ti3C2 film. This work pioneers the demo instance of flexible Ti3C2 antenna for high-speed (446.06 Mbps), large-capacity, and low-latency mmWave wireless communication.

Thermoelectric devices offer a promising route for waste-heat recovery, yet conventional modules—consisting of multiple pairs of inorganic legs soldered to rigid metal electrodes—are intrinsically brittle and nearly impossible to repair or reconfigure once fabricated. Although recent incorporation of flexible or stretchable polymeric components has improved mechanical deformability, these integrated architectures cannot be modified for new functions or restored. In this study, we propose the concept of Lego-like thermoelectric leg blocks that enable on-demand repair and reconfiguration via modular assembly. Each block operates as an independent unit comprising PDMS-based, self-healing Ag-flake-embedded composite electrodes and 3D-printed BiSbTe and BiTeSe thermoelectric legs, yielding flexible, repairable, and modular devices. Assembled devices preserve performance under bending (radius ≈ 3.4 mm), stretching (40%), and even after cutting and reassembly. Moreover, repeated disassembly/reassembly into diverse geometries proceeds without measurable loss in power output. Our Lego-like blocks provide a versatile thermoelectric platform that combines flexibility, reparability, and reconfigurability.

Airway stents play a vital role in managing central airway obstruction (CAO) caused by lung cancer and other pulmonary diseases by providing structural support to collapsed airways and restoring airflow. However, complications such as stent migration often require urgent medical intervention while early monitoring is essential to reduce the risk. Regular monitoring through bronchoscopy requires anesthesia in the hospital, which causes pain and an economic burden on patients. Computed tomography involves risky radiation and lacks the ability to provide continuous, real-time feedback outside of hospital settings. Here we report a fundamental mechanism of wireless tracking based on magnetic field in a wirelessly powered sensory ring integrated on an airway stent. The sensory ring is designed for continuous, real-time monitoring of stent position and orientation. This sensory ring, integrating an on-board magnetic sensor, and a wearable magnetic field generation system, enable accurate localization by detecting the magnetic field generated externally. The sensory ring is powered wirelessly via a charging coil, ensuring long-term operation. Our system achieves tracking accuracy of 0.5 mm and 2.2 degrees, with a temporal resolution of 0.2 Hz. Beyond migration monitoring, the sensor also detects airway deformation, offering the potential to sense pathological changes associated with lung cancer and other pulmonary conditions. By eliminating the need for radiation-based imaging or bronchoscopy, this approach enables safe, long-term surveillance of stent patency and surrounding tissue conditions. The proposed sensing mechanism and platform are also adaptable in other organs, such as the esophagus, for monitoring stent migration and deformation.

In recent years, smart contact lenses as a type of wearable device have attracted significant attention in health monitoring and disease detection. In this study, we combine a resistive sensor based on a cracked PEDOT: PSS structure with a 70 MHz double-loop gold antenna, enabling high-precision and continuous measurement of intraocular pressure (IOP). By comprehensively optimizing the sensor design, device structure, and wireless detection system, we achieved a sensitivity of 47.31 Ω/mmHg—approximately 15 times higher than conventional approach, corresponding to a resistance change 183 times larger. Both in vitro wireless IOP measurements of a porcine eye and in vivo wireless IOP measurements of rabbit eyes altered by microbead injection, using a commercial tonometer and a fabricated sensor lens, showed a strong correlation with R² values of 93% and 97%, respectively. These findings highlight the platform’s potential for long-term, non-invasive IOP monitoring, thus making a significant contribution to early diagnosis and treatment of glaucoma.

Traditional rotary motors have been developed using a variety of technologies. Electrochemically fluidic motors based on liquid metals offer unique potential advantages to the field of rotary motors. Current designs, however, are limited in rotational speed due to suboptimal extraction of mechanical motion from the liquid metal. Here, we present an electrochemically driven liquid metal rotary motor that is conceptually distinct from previous approaches by incorporating a paddle directly inserted inside the liquid metal droplet. This design, driven by pulsed electric signals, takes advantage of the internal vortices of the droplet to directly generate rotation, achieving maximum rotational speeds of 320 rpm. By directly coupling the paddle to the internal flow dynamics, this work demonstrates a more efficient and practical method for liquid metal-based actuation in an electrochemical setting. Such a system has potential applications in microfluidics and soft systems and introduces a new conceptual approach to rotary motor design.
