For many biomedical applications, acoustic power transfer is superior to other methods for powering. This chapter is devoted to ultrasonically powered devices, the concept, and the hardware necessary to make them work. A detailed description of acoustic powering and the physics of acoustic is provided to enable a full understanding of this technology. Acoustic powering and piezoelectrics as crystalline electromechanical materials are explained in the first section. Their characteristics, materials, and modeling will also be discussed. In addition, ultrasound transducers are discussed in terms of their different designs. Then, the design of the external device transmitter will be presented as a driver to transmit the power to the biomedical implantable device. Next, we present an example of an implanted brain device used for optogenetics in order to illustrate the most important blocks for harvesting the ultrasound power from the external device.

摘要

For many biomedical applications, acoustic power transfer is superior to other methods for powering. This chapter is devoted to ultrasonically powered devices, the concept, and the hardware necessary to make them work. A detailed description of acoustic powering and the physics of acoustic is provided to enable a full understanding of this technology. Acoustic powering and piezoelectrics as crystalline electromechanical materials are explained in the first section. Their characteristics, materials, and modeling will also be discussed. In addition, ultrasound transducers are discussed in terms of their different designs. Then, the design of the external device transmitter will be presented as a driver to transmit the power to the biomedical implantable device. Next, we present an example of an implanted brain device used for optogenetics in order to illustrate the most important blocks for harvesting the ultrasound power from the external device.
