Ultra‐Flexible Dual‐Band Organic Photodetectors for Visible and Near‐Infrared Sensing
An ultra‐flexible dual‐band organic photodetector with a total thickness of 5.6 µm for bio‐sensing is developed. It selectively detects visible and near‐infrared light with high sensitivity by switching the voltage. Peripheral oxygen saturation (SpO2) measurement is demonstrated using the device attached to a finger under a single light source by ...

Adhesive elastocapillary force on a cantilever beam
We measure the force–displacement curve of a cantilever beam in contact with a substrate and with an intervening capillary bridge. This elastocapillary equilibrium represents a physical model of the hairy adhesive pads of insects.

Quantum Electrometry of Non‐Volatile Space Charges in Diamond
Charges are generated when nitrogen vacancy qubits in diamond are illuminated by light. Transport and trapping in an electric field leads to the formation of large, stable space charge patterns that dynamically screen applied electric fields, impacting electric field sensing and photoelectric detection.

Improved constraints on non-Newtonian forces at 10 microns
Several recent theories suggest that light moduli or particles in "large" extra dimensions could mediate macroscopic forces exceeding gravitational strength at length scales below a millimeter.

A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Study of the Resonant Frequency of Unimorph Triangular V-shaped Piezoelectric Cantilever Energy Harvester [PDF]
: The main aim of the vibration energy harvesters is to locally power autonomous devices such as wireless sensors. Generally, power levels are low and the environmental benefit of the technology is to replace batteries rather than saving energy per se ...

Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion
This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

Broadband opto-mechanical phase shifter for photonic integrated circuits
A broadband opto-mechanical phase shifter for photonic integrated circuits is proposed and numerically investigated. The structure consists of a mode-carrying waveguide and a deformable non-mode-carrying nanostring, which are parallel with each other ...
