Abstract
A physiological sensor includes an electrical grid to activate one or more light emitters by addressing at least one row conductor and at least one column conductor. Each light emitter includes a positive terminal and a negative terminal. The physiological sensor includes a first light emitter and a second light emitter. A first contact is communicatively coupled with the positive terminal of the first light emitter, the negative terminal of the second light emitter, a first row conductor, and a first column conductor. A second contact is communicatively coupled with the negative terminal of the first light emitter, the positive terminal of the second light emitter, a second row conductor, and a second column conductor. The first light emitter is activated by addressing the first row conductor and the second column conductor. The second light emitter is activated by addressing the second row conductor and the first column conductor.
