“…Figure 3 a shows the 3D view of our model for the computational experiment, and Figure 3 b–d respectively show the side, top, and isometric views of the simplified schematic. The cavity structure was asymmetric in the up and down directions as in [ 7 , 8 , 9 , 10 ]. The heater loop consisted of four circular arcs subtending 45° and placed on a circle with a radius of 0.4 L , where L is the reference length.…”

“…Figure 2 b shows the third method. A cavity structure is created that is asymmetric in the up and down directions [ 7 , 8 , 9 , 10 ], and heat and temperature sensors are placed on the same plane. Because the shape of the deformed heat bubble varies according to the magnitude and sign of the acceleration in the z -direction, the measured temperature can determine the magnitude and sign of the acceleration.…”

The sensor response has been reported to become highly nonlinear when the acceleration added to a thermal accelerator is very large, so the same response can be observed for two accelerations with different magnitudes and opposite signs. Some papers have reported the frequency response for the horizontal acceleration to be a first-order system, while others have reported it to be a second-order system. The response for the vertical acceleration has not been studied. In this study, computational experiments were performed to examine the step and frequency responses of a three-axis thermal accelerometer. The results showed that monitoring the temperatures at two positions and making use of cross-axis sensitivity allow a unique acceleration to be determined even when the range of the vertical acceleration is very large (e.g., −10,000–10,000 g). The frequency response was proven to be a second-order system for horizontal acceleration and a third-order system for vertical acceleration.
