Hi All, my system have a set of power coils and a set of data coils. Ideally, we want the coupling coefficient between the power coil and the data coil to be zero to minimize the interference between them, espcially they are operating in a closed frequency range.
In this paper "Enabling Wireless Powering and Telemetry for Peripheral Nerve Implants" (IEEE Journal of Biomedical and Health Informatics, 2015), the authors mentioned the coupling coefficient between power Tx and data Tx coils should be less than 0.05 to garantee the detection of the data.
Now I have my power Tx coil (760308103307) and data Tx coil (760308101302), both from Wurth. I am wondering is there any way to characterize this coefficient by doing some time/frequency domain test? Or can we have some idea of estinate the coupling coefficient number by reading the datasheet?
Thank you!
