An insertable into a human body article is coated with a coating of electret structure. The strap has a hoop attachment end and a contact attachment end opposite the hoop attachment end. When the amount of time for data associated with the data set to fill the buffer exceeds the amount of time for the far-end PHY to transition to the first far-end PHY power state, a data delay indicator is transmitted to the MAC to preempt the MAC from transmitting the remaining amount of data.
