This paper reports on the triaxial force measurement
during flapping flight of a fruit fly (Drosophila
melanogaster). The total flight force was measured by a
triaxial force sensor. The sensor consists of a cantilever
probe, two sensing beams and four wiring beams. The total
size of the sensor was 2 mm ~ 3 mm ~ 0.5 mm. A fruit fly
was attached to the tip of the cantilever probe. The triaxial
forces were measured when the fruit fly flapped. The
measured force varied in synchronization with the flapping
frequency of 240 Hz. The maximum forces in both lift and
thrust directions were approximately 40 ƒÊN.
