A novel silicon sensing element is developed using microfabrication te
chnology. The sensitivity of a sensor incorporating the sensing elemen
t can be increased by an order of magnitude while its stiffness and na
tural frequencies are maintained. A prototype force sensor is develope
d to verify the effectiveness of the method. Satisfactory agreements b
etween the predicted and measured sensitivites are observed, and high
resolution (20 mu N) and high fundamental frequency (2800 Hz) are also
achieved. (C) 1998 Elsevier Science S.A.
