摘要：Multi functional sensors are described. A silicon based sensor utilizes metallayers arranged as resistors around a central pair if resistors separated by a humiditysensitive polymer with one of the central resistors being a heater. This enables
temperature humidity wind speed and direction to be measured. In another embodimentan array of resistors is printed onto a flexible substrate to form the basis of an array ofsensors. A soil moisture sensor, which is also useful as a leaf wetness sensor, incorporatesa novel self calibrating capacitive sensor structure. The flexible substrate is rolled into astake that can be inserted in the soil so that below ground sensors measure soil moistureand above ground sensors measure temperature, light, humidity, wind speed anddirection.
