Neural Electrodes Based on 3D Organic Electroactive Microfibers

On the road towards electroactive covalent organic frameworks.

Covalent organic frameworks (COFs) are a novel class of porous crystalline organic materials assembled from molecular building blocks. The construction principles of these materials allow for the design of precisely controllable structures since their chemical and physical properties can be easily tuned through the selection of the building blocks and the linkage motif. Their extraordinary and ...

Electron exchange between two electrodes mediated by two electroactive adsorbates.

Experimental data for electron exchange between two electrodes covered by electroactive films are presented and discussed in terms of the Gerischer model. A model Hamiltonian is proposed for such indirect electron exchange involving two intermediate species. Explicit model calculations are performed for the case in which the coupling between the two adsorbates is weak and determines the overall...

Laser Speckle Reduction based on electroactive polymers

Optotune has developed an Electroactive Polymer Actuator-based solution to move a diffuser and drastically reduce the speckle contrast of Laser beams: the LSR-5-17 (Laser Speckle Reducer). With its integrated miniaturized electronics for HV generation and motion control, the LSR-5-17 provides a compact 27 x 21 x 6mm solution with a simple 5V micro USB interface for power supply. A miniaturized ...

Compact optical short-pass filters based on microfibers.

We demonstrate a compact short-pass filter fabricated by integrating a microfiber (approximately 1 microm in diameter) with a low-index substrate. By varying the interaction length (from 0.65 to 3 mm) between the microfiber and the substrate for wavelength-dependent evanescent leakage, the cutoff wavelength has been tuned over a wide range of 400 nm. Typical rejection loss is higher than 40 dB ...
