In the hospital and nursing home, it is expected to introduce a bed-leaving sensor system to prevent an accident such as fall from bed and injury by wandering of care recipients. A retailed sensor is able to detect the bed-leaving with small error with the load balance of the bed casters. But its evaluation is no good because care giver felt inconvenience of the shape and weight of the sensor. So, we designed a caster load sensor that is lightweight and thin shaped for improvement of the retailed sensor. The prototyped sensor could obtain the load within 10% of the error and estimate center-gravity of the bed within 38mm of the error. Then, it was confirmed that the estimate center-gravity was corresponded the behavior of a subject position on the bed. Especially, bed-leaving prediction will be possible by detecting change of center-gravity. © 2014, Japan Soc. of Med. Electronics and Biol. engineering. All rights reserved.

The purpose of this study is development a blood collection assistance system for accident prevention. In the past studies, a vein detection system by using absorbance of the hemoglobin and a needle puncture system by using the peak detection of puncture force and the blood detection by electrode were individually developed. In this study, the each system were integrated to assist the series of blood collection procedure. The needle position was calibrated by using infrared (IR) markers monitored via IR camera. The accuracy of the positioning was within 0.4mm of the error to a blood vessel model of 0.4mm diameter. The blood collection assistance system could perform the series of blood collection procedure such as positioning the needle tip to blood vessel, needle puncturing and stop. © 2014, Japan Soc. of Med.

Blood collection is being frequently performed for blood donation and clinical testing. However the skill acquisition is exclusively performed by clinical experience for patients and simulation with an arm model of silicone rubber. However, there are some problems that they are not able to reproduce the individually different of puncture reaction force by age or body habitus, furthermore the risk of accidents or distress to patients. Therefore, we focused on haptic technology that reproduces mechanically the tactile, moreover we have been developing a blood sampling simulator that can reproduce the various reaction force. We obtained the viscoelastic modules of elastic rubber by needle puncture experiment with an elastic rubber, and constructed a reaction force model that considered the changes of the reaction force depending to puncture speed. As the results of simulation depending to the puncture, the behavior of the reaction force due to the puncture speed could be reproduced. © 2014, Japan Soc. of Med. Electronics and Biol. engineering.

Lab-on-CMOS chips (LOCMOS) are sophisticated miniaturized analysis tools based on integrated circuit (IC) microchips performing various laboratory functions. We have developed a low temperature co-fired ceramic (LTCC) package for a LOCMOS application regarding cytotoxicity assessment of nanomaterials. The LTCC packaged capacitance sensor chip is designed for long-term cell viability monitoring during nanoparticle exposure. The introduced LTCC package utilizes the flip chip bonding technique, and it is biocompatible as well as able to withstand the environmental conditions required to maintain mammalian cell culture directly on the surface of a complementary metal oxide semiconductor (CMOS) integrated circuit.

In vitro uniaxial stretch model for evaluating the effect of strain along axon on damage to neurons

Diffuse axonal injury (DAI), a major component of traumatic brain injury, is associated with rapid deformation of brain tissue resulting in the stretching of neuronal axons. Focal axonal beading, which is the morphological hallmark of DAI pathology, leads to the disconnection of neurons from tissues and results in cell death. Our goal is to achieve a better understanding of neuronal tolerance and help predict the pathogenesis of DAI from mechanical loading to the head. In the present study, we developed an experimental model that subjected cultured neurons to uniaxial stretch by controlling the direction of axonal elongation with a microfluidic culture technique and examined the effect of strains along the axon on cell damage. Neurites from PC 12 cells that differentiate into neurons with structurally axon-like cylindrical protrusions by nerve growth factor were extended at 0°, 45°, and 90° relative to the tensile direction by using a fabricated polydimethylsiloxane (PDMS) piece with microgrooves in combination with a PDMS substrate. The morphology of the same neurites was observed before and after stretching with a strain of 0.22 at a strain rate of 27 s-1. As a result, swellings along neurites oriented at 0° increased immediately following stretching and were sustained for 24 h. In contrast, swellings along neurites oriented at 45° and 90° transiently increased within 1 h following stretching. Although more ruptures were observed in neurites oriented at 0° and 90° than in those oriented at 45°, the number of neurites and cells did not differ among orientation conditions. These results suggest that the difference in strain along the axon induces axonal injuries differing in type and degree. They also suggest that the strain on the axon, rather than that on the cell-cultured substrate, is important for evaluating neuronal damage. © 2014 The Japan Society of mechanical Engineers.

Deterioration diagnosis of a lead acid battery by phase change between impedance and reactance was measured. The measurement frequency of inner impedance was changed from 100 Hz to 5 kHz. The lead acid battery with 11V open terminal voltage at the charge condition of 60% was judged as enabled in case the phase of impedance was more than 35 degrees when the application limit is CCA 180 Ampere. © 2014 The Institute of Electrical Engineers of Japan.

This video presents our preliminary work towards addressing the ladder climbing event in DARPA Robotics Challenge (DRC) using DRC-Hubo robot. A ladder-climbing motion planner is developed which generates a collision-free, stable quasi-static trajectory for execution. Compliance control is enabled on arm joints to compensate for the calibration error, modeling error and control error. We have demonstrated that DRC-Hubo can robustly climb a variety of ladders in simulation and successfully climb a ship ladder on the hardware.
