Abstract Highly sensitive flexible tactile sensors that can be fabricated in a low cost and efficient way are great demand for intelligent soft robotics friendly human–machine interaction. Herein, highly sensor is developed by using bionic micropatterned polydimethylsiloxane (m‐PDMS) replicated from lotus leaf. The m‐PDMS substrate consists of high‐aspect‐ratio low‐density microtowers, covered ultrathin silver nanowires as bottom electrode. capacitive sensing device constructed sandwiching...
Abstract Flexible electronic skins (e‐skins) with high sensitivity and broad‐range pressure sensing are highly desired in artificial intelligence, human–machine interaction. Capacitive‐type e‐skins have a simple configuration, but the change dimensions of dielectric layer is often quite limited, although introducing surface microstructures might improve some extent. Moreover, such structures typically require costly microfabrication methods to fabricate. Here, low‐cost microstructured ionic...
Nature has long offered human beings with useful materials. Herein, plant materials including flowers and leaves have been directly used as the dielectric material in flexible capacitive electronic skin (e-skin), which simply consists of a dried flower petal or leaf sandwiched by two electrodes. The is 3D cell wall network plays like compressible metamaterial that elastically collapses upon pressing plus some specific surface structures, thus device can sensitively respond to pressure. works...

Skin-like electronics require materials that are conducting, soft, intrinsically stretchable, and highly robust. However, electronic devices often consist of multilayers, the failure mostly starts from debonding layers because poor interfacial adhesion large mechanical mismatch. Herein, we introduce a fully organic stretchable electrode achieves high robustness by grafting substrate to improve introducing deep folds wrinkles stretchability. The exhibits sheet resistance 90 Ω/□ negligible...
Inspired by biological diversity and uniqueness, the concept of bionic optical physical unclonable functions (PUFs) is proposed. Production simple, low-cost, green environmentally friendly. The extracted binary codes from PUFs are random, unclonable, robust enough for applications in entity authentication encrypted communication.
Abstract Flexible pressure sensors that respond to normal contact force, play a pivotal role in wide range of applications, such as health monitoring, robotic perception and artificial intelligence. With the increasing demand for specialized high-performance sensors, key parameters these including sensitivity, detection range, linearity, response time, cyclic stability, etc, have become crucial factors determining their suitability specific applications. The characterization has therefore an...
We propose an approach for fast random number generation based on homemade optical physical unclonable functions (PUFs). The PUF is illuminated with input laser wavefront of continuous modulation to obtain different speckle patterns. Random numbers are fully extracted from patterns through a simple post-processing algorithm. Our proof-of-principle experiment achieves total rate 0.96 Gbit/s verified randomness, which far faster than previous optical-PUF-based schemes. results demonstrate that...
