Abstract: Several types of piezoelectric MEMS vibration energy harvesters are described herein as well as methods of fabricating the vibration energy harvesters. The vibration energy harvesters generally comprise a serpentine structure having a central longitudinal axis; a piezoelectric film deposited on a surface of the serpentine structure; a central mass located at a mid-portion of the central longitudinal axis; two lateral masses positioned at opposing corners of the serpentine structure; anchor points at two other opposing corners of the serpentine structure; and upper and lower electrode layers. The energy harvesters have a 180 degree rotational symmetry about the central mass and when the serpentine structure experiences a strain, the piezoelectric film generates a voltage. The geometry of the energy harvesters allows for lower frequency and wider bandwidth operation as well as higher power density.

Abstract: The present application relates, for example, to substrates for surface enhanced Raman spectroscopy (SERS), to methods for their preparation and to uses of such SERS substrates in methods for the detection of an analyte in a sample. The SERS substrates of the present application comprise a support material, a layer of a SERS-active metal on the support material, and a layer of magnetically active nanoparticles on the layer of the SERS-active metal. The methods of preparing such SERS substrates comprise depositing a layer of a SERS-active metal on a support material, and depositing a layer of magnetically active nanoparticles on the layer of the SERS-active metal.
