Freestanding PZT Films for Integrated Wearable Sensing and Intelligent Acoustic Recognition
Advanced Science, EarlyView.A freestanding epitaxial PZT/LaNiO3/Pt heterostructure is achieved via water‐assisted delamination from mica, effectively eliminating substrate‐induced clamping and releasing intrinsic ferroelectricity. The released film exhibits substantially enhanced remanent polarization and piezoelectric response, delivering excellent mechanical flexibility and ...

Advanced Science, EarlyView.A Pt/TaOx/V single‐spike TTFS encoder achieves ultralow‐voltage (∼0.35 V), high‐speed (∼100 ns) operation with simplified circuitry. Integrating bipolar nonuniform temporal encoding with a spiking‐DFT neuron model enables a neuromorphic FFT framework. Device‐calibrated simulations demonstrate high spectral fidelity across multitone, speech, and chirp ...

Habitat‐Specific Design Strategies for Untethered Soft Robots
Advanced Science, EarlyView.Habitat shapes the design of untethered soft robots. Across land, water, air, and living tissues, environmental constraints govern viable combinations of compliant structures, actuation mechanisms, and energy delivery. This review connects these constraints with robotic performance and identifies design principles for advancing adaptable, durable, and ...
