Angular displacement of a flexible substrate is determined based on an electrical change of a mm-wave circuit associated with the flexible substrate. This electrical change may relate to, for example, one or more of a phase shift, an amplitude shift, a frequency shift, or a pulse shift. In some implementations the flexible substrate may include conductors on multiple layers whereby an angular displacement of the flexible substrate causes a relative displacement between conductors of different layers, thereby inducing the electrical change of the mm-wave circuit. |
