In case that users exercise for healthcare, the users require the effect of exercise. The most useful index of the effect by exercise is "Energy Consumption", and the most accurate measuring method of energy consumption is to measure respiratory metabolism by Douglas bag that is not wearable instruments. The object of this study is to construct the "Wearable Information Healthcare System". As the first step of this study, the algorithm of accurate measuring of energy consumption especially in the low-load area and wearable energy consumption measuring system are development. The new algorithm is evaluated in the field test, and the calculated value is agreed to the true value.

As Silicon diaphragm piezoresistive pressure sensors have large temperature coefficient. To measure pressure as high accuracy, temperature compensating was indispensable. On current model, variable resistance or capacitance used to be mounted on board for calibration and temperature compensating. The method has some problems such as Reliability and Mass-Production facility. To improve the problems, we adopted digital signal trimming for calibration and temperature compensating, this realized high accurate pressure sensing.

Stress characteristics in adhesive scarf joints of dissimilar adherends subjected to impact loads are analyzed in an elastic region using three-dimensional FEM. An impact load is applied to a joint by dropping a weight. The end of the upper adherend is fixed and the other end of the lower adherend is subjected to an impact load. The effects of scarf angles and combination types of the adherends, the adhesive thickness and Young's modulus of the adhesive on the stress behavior at the interfaces are examined. In addition, experiments were carried out to measure the strain response of the adhesive scarf joints subjected to impact tensile loads using strain gauges. A agreement is seen between the tendencies of the analytical and experimental results.
