This research employs an expressive robot to elicit affective response in young children and explore correlations between autonomously-detected play, affective response and developmental ability. In this study, we introduce a new, affective interface that combines sound, color, movement and context to simulate the expression of emotions. Our approach exploits social contingencies to emphasize the...
This work presents an open-loop, fully differential capacitive MEMS accelerometer implemented in CMOS technology. The mathematical model of this open-loop system is derived, which considers non-ideal factors in circuits such as nonlinear distortion and noises. These non-ideal factors have been discussed through system level simulation using MATLAB. Simulation results show that the system has good...
This paper reports a novel monolithic-integrated three-axis convective accelerometer by using a thermopile-embedded curving cantilever for Z-axis sensing. The cantilever down-curving is caused by pneumatic-effect of mutually stress-mismatched two layers. The convective accelerometer consists of a micro heater and several pairs of sensing thermopiles for 3-D temperature-difference detection. In Z-axis...
Abstract-This paper presents a novel composite sensor that is monolithically integrated with an accelerometer, a pressure sensor, and a thermometer by using a single-side-processed micromachining technique. Such composite sensors are highly demanded in tire pressure monitoring system (TPMS) applications. Based on heat convection, the accelerometer consists of a microheater and a pair of detector to...
The paper presents a novel single-side micromachined composite sensor, with a piezoresistive pressure sensor, a thermal-convection accelerometer and a thermometer monolithically integrated in one 2.5times2.5 mm2 chip, for low-cost production and applications such as tire-pressure monitoring systems (TPMS). The accelerometer is based on heat convection, including a micro heater and two pairs of micro...
