A device for integrating and indicating a parameter over, comprising: a first electrode (), a second electrode (), an electrolyte (), which is in contact with the first electrode and in consuming contact with a consumption portion () of the second electrode, at least two indicators (I, I, I), which are connected to the consumption portion () at a respective connecting point (P, P, P). The electrolyte () and the consumption portion () are selected such that when a voltage is applied over the electrodes (), the consumption portion () is consumed at a predetermined rate, wherein the indicators (I, I, I) are arranged to switch states in response to a consumption frontier (F, F) of the consumption portion reaching or passing a connecting point (P, P, P) associated with the respective indicator (I, I, I), wherein at least one of the indicators is a binary (on/off) indicator.

Device for integrating and indicating a parameter over time

A device for determining a parameter history indication of at least one external parameter includes, in at least one embodiment, a first electrode portion, in consuming contact with a first electrolyte, and a second electrode portion, in consuming contact with a second electrolyte. A consumption process of the second electrode portion, in at least one embodiment, is controllable by an amount of consumption of said first electrode portion. The electrolytes are so arranged that consumption rates of the first electrode portion and the second electrode portion present different dependencies on the at least one external parameter. A kit of parts including such a device, and a method for determining a parameter history indication of at least one external parameter are also disclosed.
