Abstract
A wellbore assembly includes a housing member, an outer wellbore member, and a second wellbore member, with an outer sensor located in the annulus between the outer wellbore member and the second wellbore member. The outer sensor can sense a condition of the annulus, such as pressure or temperature, and transmit data through a solid portion of the sidewall of the outer wellbore member to a signal receiver located on the housing member. In one embodiment, the signal receiver can transmit an electromagnetic field to inductively charge a power supply on the outer sensor.
