Abstract: An apparatus and a method for detecting insect infestation are described. The apparatus includes a cylindrical capacitive sensor including a first semi-cylindrical electrode plate and a second semi-cylindrical electrode plate, wherein the first semi and second semi-cylindrical electrode plates are configured to wrap around the test tree trunk and a processing circuitry, which is configured to measure a capacitance of the test tree trunk when positioned between the first semi-cylindrical electrode plate and the second semi-cylindrical electrode plate and provide a measured capacitance, compare the measured capacitance of the test tree trunk to a reference capacitance of a reference tree trunk, and determine whether an insect infestation is present in the test tree trunk. The cylindrical capacitive sensor can further include another two types of electrode configurations: two pairs of cylindrical electrode strips and two cylindrical electrode rings, wherein the two pairs of cylindrical electrode strips are further configured to positively charge a first pair of cylindrical electrode strips wherein the two the cylindrical electrode strips are oppositely positioned and negatively charge a second pair of cylindrical electrode strips wherein the two cylindrical electrode strips are oppositely positioned, and the two cylindrical electrode rings is further configured to positively charge a first cylindrical electrode ring and negatively charge a second cylindrical electrode ring.

Abstract: An apparatus and a method of detecting insect infestation condition are described. The apparatus can include: a microstrip patch antenna, configured to mount on a flattened surface of a test tree trunk and transmit a microwave signal; a measurement device, configured to measure a microwave reflection response of the test tree trunk in response to the microwave signal from the microstrip patch antenna; a storage medium, configured to store the measured microwave reflection response of the test tree trunk, one or more microwave reflection responses of one or more reference tree trunks, a program for comparing microwave reflection responses, and a program for identifying an insect infestation condition of the test tree trunk, and a processing circuitry, configured to read the stored microwave reflection responses, compare the measured microwave reflection response of the test tree trunk to the microwave reflection responses of one or more reference tree trunks, and identify the insect infestation condition of the test tree trunk.
