In this paper, we present a conceptual framework and a physical prototype of sensor-integrated geometric blocks (SIG-Blocks) for automated play-based assessment of cognitive and fine-motor skills. SIG-Blocks enable remote and real-time monitoring of a person's behavior and performance during play through integrated sensors and wireless communication(More)
— This paper presents OrigamiBot-I, a thread-actuated origami robot, to demonstrate a physical application of an origami design for robotic manipulation and locomotion. The selected design can generate twisting and bending motions by pulling, pushing, or torsional force applied to the origami structure. Thread-based actuation also enables various shapes and(More)
Parkinson's disease (PD) and Alzheimer's disease (AD) can coexist in severely affected; elderly patients. Since they have different pathological causes and lesions and consequently require different treatments; it is critical to distinguish PD-related dementia (PD-D) from AD. Conventional electroencephalograph (EEG) analysis has produced poor results. This(More)
Patients who undergo inter-hospital transfer experience increased relative mortality, ranging from 10 to 100% higher than non-transferred patients. The high-cost, increased risk of complications and poor outcomes of transferred patients warrant the critical examination of potential causes. One of the major causes may be the external stressors that patients(More)
