Sensor device, method and sensor for determining a relative concentration of a first type of ions in relation to a second type of ions which are dissolved in a liquid drops

摘要

A sensor device (100) according to one embodiment, a semiconductor substrate (110) on a plurality of channels (120), wherein the channels (120) has a cavity (140) and a measuring electrode (150), as well as a counter electrode (160), which is arranged so that they come into contact with the hollow space (120), wherein the hollow space (120), the measuring electrode (150) and the counter electrode (160) are so arranged that they receive a liquid droplet and make it possible, a voltage at the liquid drops, to lay.
