Abstract
The present invention provides a surface tension assisted film forming method to prepare a flexible, patterned piezoceramic composite for use in a variety of electronics. The present method allows tuning mechanical and piezoelectric properties of the resulting composite by simply adjusting one or few parameters used during the piezoceramic film forming and/or composite forming procedures in the absence of any complex transferring techniques that are commonly used in conventional methods. The present invention also allows customizing patterns (two-dimensional or three-dimensional) on the piezoceramic framework to result in a piezoelectric composite that is able to provide anisotropic piezoelectric responses to different loads whilst still having a constant electrical output over a long-time deformation.
