1. A method for measuring electrodermal activity (EDA), the method comprising:
detecting, using one or more sensors, contact with a sensing surface, the sensing surface having a plurality of electrode pairs, each electrode pair including a first electrode and a second electrode, the first electrode and the second electrode being electrically isolated from each other, the plurality of electrode pairs being electrically isolated from each other, the plurality of electrode pairs being substantially parallel to each other, a distance between two directly adjacent electrode pairs being larger than a distance between the first electrode and a second electrode of each electrode pair, no intervening conductive structure is located between the two directly adjacent electrode pairs;
responsive to detecting the contact with the sensing surface, selecting one or more electrode pairs to activate; and
responsive to selecting one or more electrode pairs to activate, causing the selected one or more electrode pairs to be activated.
