摘要：A sensor (10) is disclosed, which uses a transmission principle beyond RF-signalsand which sensor doesn't need an electrical circuitry. The principle is based on indicationmeans, which built by a contrast interface (32) contrasting two mediums and whichcontrast interface is readable by sound or radiation. Advantageous embodiments of thepresent invention include an amplification system via micro channels (20) or a micro gear,which transform a change of length with a very high accuracy and resolution. In a furtherembodiment a compensation of temperature does not influence the measurement of aforce.
