摘要：
In this paper, an improved touch probe sensor device for higher sensitivity and low contact force is reported. In order to improve the resolution, we have evaluated the sensitivity and fabricated a miniaturized sensor. The sensor transducer was 3 mm long and had higher resonance frequency. The resonance frequency of the vibrator was 937 kHz. Evaluated sensitivity was 1.0 x 10(-1) mV/nm. This value equals five times larger than that of a previous sensor. Miniaturization of the sensor device carried smaller vibration operation and higher sensitivity. (C) 2002 Elsevier Science B.V. All rights reserved.
