1. An electronic device, comprising:
a printed circuit board, the printed circuit board comprising:
a conductive base layer, wherein the conductive base layer is an electrode to produce a signal indicative of a change in an omnidirectional electrostatic field corresponding to a moving object;
a via coupled to the conductive base layer, wherein the via is disposed through an intermediate layer of the printed circuit board; and
an integrated circuit coupled to the via, wherein the integrated circuit is to detect, using an artificial neural network, a direction of the moving object in the omnidirectional electrostatic field based on a feature of the signal.
