- High Sensitivity Micro-machined Piezoresistive Strain SensorPublication . Caseiro, D.; Santos, S.; Ferreira, Carlos Daniel Henriques; Neves, CarlosThis paper presents a micro-machined piezoresistive sensor capable of measuring very small strains. The sensor design, based on piezoresistive sensing technology, was optimized by the numerical method using Finite Element Method (FEM) to enhance sensibility. The high sensibility is achieved through a reduction of section and through the action of the bending moment. As a result, a sensor with a sensitivity of 569.4608 μV/V/με, which can be fabricated by the SensoNor MultiMEMS process, is proposed. Furthermore, practical essays with macro prototypes confirmed and validated the numerical analysis. Such a sensor can be a direct replacement for the strain gauges and its very high sensitivity opens the door to many other applications, that otherwise would not be possible.
- Mysterious Bones Unearthed:Development of an Online Therapeuticserious Game for Children with Attention Deficit-hyperactivity DisorderPublication . Rijo, R.; Costa, P.; Bastos, D.; Bastos, D.; Matos, P.; Silva, A.; Ferrinho, J.; Almeida, N.; Oliveira, A.; Xavier, S.; Santos, S.; Oliveira, C.; Brites, S.; Martins, V.; Pereira, A.; Fernandes, S.Attention deficit-Hyperactivity Disorder is a disease that affects 3 to 5 percent of children globally. The treatment roots on medication and behavioral exercises. There are unwanted, documented, side effects of the medication, and the behavioral exercises are very demanding for children. In this context the goal of the present research was the development of a serious game for children with 6-8 years old with behavioral exercises as the basis for the action of the game, using a ludic approach. This ludic approach intends to increase the motivation for the game. The present work is part of the research project Therapy4All. The objective of the project is not to replace the traditional form of treatment, but to complement it by allowing a physician to maintain her/his patients under supervision between their regular consultations. The goalis the development of research on serious games to provide patients a better control of their symptoms more than with just traditional therapy. Our first results, with a very small sample, show encouraging improvements in the children's competencies.
