1 Introduction The challenge of traditional pressure sensors in differentiating loading directions originates from the isotropic nature of sensing materials and structures, which typically generates similar deformations upon pressing in any direction.[1, 2] Such features have severely limited their practical application when considering the multidimensionality of mechanical stimuli.[3] To overcome these obstacles, anisotropic pressure sensors are necessary for recognizing complex pressure...

Piezoelectric energy harvesters (PEHs) with porous structures, such as piezoelectric elastic sponges, exhibit high force-to-electricity conversion efficiencies owing to their excellent compression recovery properties. However, conventional preparation methods are limited to producing bulk-form sponge-like PEHs and fail to create more elaborate three-dimensional (3D) structures that could enhance conversion efficiency.
