A theoretical approach to facilitating transition phase motion in a positively buoyant autonomous underwater vehicle [PDF]
, 2009 Positively buoyant autonomous underwater vehicles (AUVs) operate at survey speeds with a pitch angle that ismaintained through application of the control surfaces, sufficient to generate hydrodynamic forces to counteract theexcess buoyancy. To facilitate

Self‐Healing and Stretchable Synaptic Transistor
Advanced Functional Materials, EarlyView.A self‐healing stretchable synaptic transistor (3S‐T) is realized using a p‐PVDF‐HFP‐DBP/PDMS‐MPU‐IU bilayer as gate insulator, where dipole‐dipole interaction enhances polarization to achieve a large memory window. Leveraging its neuronal biomimicry, the synaptic transistor demonstrates electrically compatibility with the biological brain. Furthermore,

Advanced Functional Materials, EarlyView.Porous Ecoflex/PTFE composite with encapsulated liquid generates electricity through ionic migration induced by dynamic pore deformation, creating non‐uniform electric fields that drive charge induction on electrodes. This mechanism enhances charge transfer and ensures stable contact electrification performance, achieving 12 V and 4 nC with consistent ...

Underwater Mixed Environments [PDF]
, 2015 In this chapter we give a systematic overview over Virtual Reality (VR) and Augmented Reality (AR) in underwater settings. Based on a novel classification scheme we illustrate the broad range of available and future implementation options. Whilst we find a variety of previous work on creating and using virtual underwater worlds, quite few examples of ...
