Abstract More than 70% of human information comes from vision. The eye is one the most attractive sensing sites to collect biological parameters. However, it urgent develop a cost‐effective and easy‐to‐use approach monitor eyeball in minimally invasive way instead current smart contact lenses or camera‐based eyeglasses. Here, biomimetic mineralization strategy developed prepare large‐grained perovskite film on glass with prepared ITO electrodes, which displays on–off ratio close 300 times at 500 Lux light intensity, responsiveness reaches 22.09 A W −1 . eyeglasses composed perovskite‐based photodetectors can directly convert visual stimuli reflective eyeballs into electrical signals all circumstances. After scaling up pretraining data model size, achieve noncontact monitoring movement recognition angle 5°, be used unobtrusively drive car great freedom. based provide approaches for movements, will show potential applications man‐machine control, augmented reality, individual healthcare, etc.

The development of low-cost and high-performance flexible polymer-based piezoresistive sensors is great significance in the fields human–machine interaction, motion monitoring, wearable technologies. However, traditional are generally prepared by immersion spray-coating conductive fillers on polymer foams, easy to fall off from framework under external stress, which makes it difficult for sensor meet long-term use requirements. In this paper, a stable foam was fabricated cofoaming natural latex poly(3,4-ethylenedioxythiophene) (PEDOT):poly(styrenesulfonate) (PSS) fabricate NR/PEDOT:PSS foam. PEDOT can be uniformly distributed NR latex. PSS with emulsification feature also introduces secondary pore This as-prepared hierarchical porous structure has merits fabrication, robust mechanical properties, excellent flexibility, good reproducibility (1000 cycles), durability. Additionally, exhibits wide sensing range, fast response (140 ms), recovery time (120 ms). These advantages enable effectively differentiate between movements different joints various behaviors. Furthermore, provide capabilities gait monitoring warning. Overall, demonstrates significant potential applications electronics.

Accurate, effective, and continuous monitoring of pressure, moisture, temperature is essential for routine health assessments professional patient care. In this study, we present a fully integrated multiparameter passive wireless sensor (MWS) that employs mechanical-electrical dual-gradient structure design. The unique gradient porous endows the MWS with significant advantages in terms detection dimensions (pressure, temperature), sensitivity, stability. Compared to single mechanical designs, demonstrates 2.6 times higher pressure sensitivity 5-tier moisture capability. By bridging technology gap between high-precision sensing, communication, energy management, capable measuring multiple physiological parameters, including breath, ballistocardiograph, at points, providing real-time state subjects. This work offers valuable quantitative insights caregivers paves way advancements personal healthcare management.
