This paper reports a simple method to capture and rotate a bio-object at a controllable speed in direction of vertical plane. This method intends to implement its function without contact in an open space for biological application such as dynamically monitoring, orientation setting, and mechanical stimulation induced by fluidic shear force. To verify this principle, calculation process of necessary flow rate for generating enough operating force on the cell is conducted with CFD. An open-space microchip with several orifices (diameter is 100 μm) is designed and fabricated. Then the manipulating demonstrations are conducted. On the calculated conditions, the rotation of target cell is successfully obtained. The relation between the object's velocity, flow rate, and operating force is clarified.

In this study, the cell sheet-based technology was able to control cell orientation in 3D engineered tissue construct. Using a micropatterned thermoresponsive surface, human cells such as fibroblasts and myoblasts were aligned on the surface, and manipulated as a single cell sheet by reducing the culture temperature to 20°C. Consequently, their anisotropic cell sheets can be layered using gelatin gel to produce 3D tissue constructs with the desired anisotropy. For example, two fibroblast sheets layered perpendicularly showed three-dimensionally different cell orientation as designed. By induce differentiation of myoblasts forming an anisotropic cell sheet into myotubes, a myotube construct with a single orientation was possible to be created. Since the combined use of the anisotropic cell sheet and cell sheet manipulation technique allows us to create complex tissue that requires the three-dimensional control of their anisotropies, we believe that it has a potential to be one of the next-generation tissue engineering technology.

In this research, we focused on the energy consumed in the levitation mechanism used in an inchworm-type microactuator when the mechanism is levitated. We use a power meter for the measurement of the energy required for levitation. We estimate the levitation height by comparing the levitation height measured by a displacement sensor and the power consumption measured by a power meter. The levitation height measured with the displacement sensor shows the similar trend obtained with the power used in the levitation mechanism. We are studying a piezoelectric actuator used in a levitation mechanism. The levitation mechanism levitates using a squeeze effect caused by the vertical vibration of the piezoelectric element. Frictional force control is realized by using levitation mechanisms, and the microactuator moves by the principle of inchworm. We usually measure the displacement of the levitation mechanisms by the use of a displacement sensor. However, the measurement of the vertical direction is difficult because there are a number of limitations. Therefore, a measurement method without displacement sensors in the vertical direction is required. The estimation method proposed in this paper can extend the working range of the microactuators. The energy consumed in the microactuator includes the information of the actuator. We measure the energy and the state simultaneously, and levitation height used for levitation is estimated. The measured and estimated levitation height as a function of the operation frequency is also discussed.

We present single-cell pairing of different types of cells with a rapid manipulation based on positive dielectrophoresis (p-DEP). The DEP device for the manipulation of cells consisted of a microfluidic channel with an upper indium tin oxide (ITO) electrode and a lower ITO electrode with 10,000 (100 × 100) microwells. The width (14 μm) and depth (25 μm) of the individual microwells restricted the size to two vertically aligned cells. Cells stained in blue and stained in green were continuously trapped in the microwells. Cells were paired within only 1 min and a pairing efficiency of 53% was achieved.

In this paper, effects of cell-cell adhesion or cell-substrate adhesion on cellular differentiation are evaluated using a microwell array having convertible culture surface (CCS microwell array). The CCS microwell array is used for limitation of culture area and regulation of the adhesion timing. The CCS microwell array is fabricated by photolithography of SU-8 photoresist on the cover slip, and coating of the alginate thin film on the microwell bottoms. The alginate thin film is used as a material that inhibits adhesion of cells. It uses an alginate film that is not toxic to cells and can be removed by ethylendiaminetetraacetate (EDTA), which is calcium chelator, at arbitrary timing during cell culture. A single spheroid is formed by cell-cell adhesion in microwells because cells can't adhere to the culture surface by adhesion inhibition effect of the alginate thin film. When the culture surface is converted to cell-adhesiveness surface by removing alginate thin film, cells adhere to the microwell bottoms. The transition of the diameter of spheroid cultured in the CCS microwell array was evaluated by observation of an inverted microscope. Also, cellular differentiation behavior under four kinds of conditions was compared for verification of cell-cell or cell-substrate adhesion effect. This result shows the efficiency of induction of cellular differentiation was increased by cell culture in the CCS microwell array compared with three kinds of other culture conditions.

Spheroid is formed by making it agitate and circle in cell suspension. However, the injection of the cells used as pieces of spheroids, the recovery at the time of tissue formation, exchange of a culture medium, etc. are performed manually, and it is hard to say that efficient organization construction is performed. Thus, we suggest utility and possibility of applying microfluidics for formation of toroidal-like spheroid. Microfluidic devices to generate rotational flow were fabricated, and we conducted experiments using mouse embryo fibroblast cell.

In conventional micro-fluidic devices, it is difficult to transport gaseous and solid as well as liquid, or change the size of the channel depending on cell proliferation. We have developed a reconfigurable microfluidic channel with movable sidewalls by mechanically discretized sidewalls with laterally aligned rectangular pins. However, the leakage of fluid through the gap between pins by capillary action is problematic. To address these problems, we have introduced hydrocarbon wax and silicone adhesive to fill the gap, and have studied the effect of pin-to-pin gaps and the surface roughness of pins on the leakage.

Copper oxide anti-reflection structures were designed by rigorous coupled wave analysis for thin-film thermoelectric solar generator. We proposed thin-film thermoelectric generator with the anti-reflection structure on the hot side of pn junction. When infrared solar light from 800 to 1200 nm wavelength is irradiated to the thermoelectric generator, the anti-reflection structure on the hot side generates the temperature gradient between the hot side and cold side of pn junction. When the cross-sectional geometry of the anti-reflection structures was hemisphere which was geometrically approximated pyramid one, the reflectance from 800 to 1200 nm wavelength was reduced than flat and binary ones. The reflectance of solar light was obtained by considering the solar light spectra and its polarization. By assuming that the average of TM and TE polarized light was the reflectance of solar light, the reflectance was reduced to be 9.6% when the period of the anti-reflection structure was 700 nm. Taking into account of the reflectance of Cu on cold side 99%, this large reflectance difference is expected to generate a large temperature gradient between hot side and cold side.

In this paper, we propose a face recognition method for tracking, detecting and recognizing the faces of children with Autism Spectrum Disorder (ASD) for robotic assistive therapy application. ASD is a brain developmental disorder that manifests itself through a person's behavior and social-communication skill [1]. Face recognition stage is an essential element in robotic assistive therapy since it is the first interaction step that occurs between autistic children and robot. The algorithm aims to encourage autistic children to interact and to capture their attention using a robot that recognizes their faces. This is to establish a beneficial training environment for autistic children before engaging further in the training module.
