Abstract
Implantable medical devices have been developed for disease monitoring and treatment. One example is the wireless neural stimulator. In our previous study, wireless power and wireless device control using ultrasound was proposed. Efficient ultrasound wireless power transmission and data communication were demonstrated on animals. It is clearly demonstrated that the focusing capability at depth of ultrasound has advantages over electromagnetic waves in the applications of wireless implantable medical devices. Another issue in this context is the detection of the implanted device. This is critical as the acoustic energy needs to focus at the right location for effective power and data transmission. In the current study, our hypothesis is that by properly designing microstructures of the housing of the implantable device, specific spectral characteristics can be achieved and utilized for effective detection.
