    We fabricated an MRI-compatible force sensor with enclosed air using pressure transmission. The fabricated force sensor consists of a contact portion, sensing portions, and connecting pipes. When force was applied to the contact portion, the internal air pressure increased with a deformation of the contact portion, and is transmitted to the sensing portion through the connecting pipes. In the sensing portion, the change in air pressure is detected by a change in the resistance of a piezoresistive cantilever. Since using this air pressure transmission, the sensing portion can be placed away from the magnet of the MRI. Therefore, the force sensor does not interfere with the magnetic field, and it can be used in the magnet of an MRI.

    Herein we examined the extent of replicability of the PDMS microchamber device transferred from the master mold with complex 3D structures fabricated via micro stereolithography. Due to the elastomeric properties of PDMS, the reversely tapered micromold, with the diameter ratio of ∼5 from the largest to the narrowest part, was precisely transferred without breaking. We obtained the mathematical model to estimate the stress exerted on the mold during the demolding process. Finally, we tested the applicability of this unusual microchamber for single-cell trapping and an enzyme assay.

Our device comprises a wrist band device for the arterial tonometry method and a ring device for the photoplethysmography method. Blood pressure was calculated from the pulse transit time between the ring device and wristband device. Furthermore, we compared the accuracy of blood pressure measured by the arterial tonometry method and that calculated from the pulse transit time and multiple regression equation. The correlation coefficient of the tonometry method was improved from 0.90 to 0.99 using the combination of both cuffless blood pressure measurement methods.</p>

    This paper reports on a micro saddle coil for local high-resolution magnetic resonance imaging (MRI) fabricated by embedding a flexible coil pattern into a polydimethyilsiloxane (PDMS) tube. We can change the sensitivity of the micro coil by deforming the shape of the coil from a saddle-shaped mode to a planar-shaped mode. The inductance, the resistance, and the Q-factor of the coil in the saddle-shaped mode were 2.45 mu H, 3.31 Omega, and 39.9, respectively. Those of the planar-shaped mode were 3.07 mu H, 3.92 Omega, and 42.9, respectively. In MRI acquired in saddle-shaped mode, a large visible area existed around the coil. Although the sensitive area was considerably reduced in the planar-shaped mode, clear MRI images were obtained. The signal-to-noise ratios (SNR) of the saddle-shaped and planar-shaped modes were 194.9 and 505.9, respectively, at voxel size of 2.0 x 2.0 x 2.0 mm(3) and 11.7 and 37.4, respectively, at voxel size of 0.5 x 0.5 x 1.0 mm(3). The sensitivity of the saddle-shaped and the planar-shaped modes were about 3 times and 10 times higher, respectively, than those of the medical head coil at both voxel sizes. Thus, the micro saddle coil enabled large-area imaging and highly sensitive imaging by switching the shape of the coil.

    This paper reports on a bicone-shaped micro coil for magnetic resonance imaging (MRI) that has a low resistance and a low parasitic capacitance. The micro coil was fabricated by vacuum evaporation and electroplating of Cu onto the stepped helical structures made by three-dimensional (3D) printer. Because the helical structure was fixed on the rotary-tilted stage, Cu was evaporated only on the wiring part of the helical structure. Furthermore, we could decrease the resistance by electroplating and by increasing the linewidth of the wiring fabricated by the 3D printer. Using the fabricated bicone-shaped coil, we obtained high signal-to-noise ratio (SNR) MRI images.

    In this study, we fabricate a the blood pressure measurement device based on the arterial tonometry method with a convex micro pressure sensor array for reducing a cross talk of the sensor. The size of our device is 30 x 30 x 5.8 mm(3). It has 11 pressure sensors that are 130 x 250 x 20 mu m(3) in size. Because each pressure sensor element has a convex surface shape, the pressure measured by each sensor element has little effect on the others. Thus, a clear blood pressure pulse wave can be measured by reducing the cross talk of the sensor.

    This paper reports on a cone-shaped micro coil for measuring an NMR (Nuclear Magnetic Resonance) signal of an MRI (Magnetic Resonance Imaging). A three dimensional cone-shaped micro coil was fabricated by pulling up an outer frame of a spiral patterned micro coil. Since there are supporting parts between the wiring, the cone-shaped micro coil has uniform pitch. By using this process, we fabricated the cone-shaped micro coil of 30 mm in diameter and 8 mm in height. The resistance and Q-factor of the coil were 2.14 Omega and 32.3 at 8.5 MHz. As a demonstration of MRI by the cone-shaped micro coil, we acquired MR images of a quail egg and an okra.

    This paper reports on a fabrication method of sub-micrometer size tunable planar gaps for micro Fabry-Perot interferometers. We made an upper unit with a movable sub-micrometer step and a lower unit, separately. The upper unit was picked up and transferred to the lower unit by the stamping apparatus, and bonded to the lower unit by fusion bonding. Since the force during fusion bonding acts within a few nanometers only, the sub-micrometer size planar gap can be built. By using this fabrication method, we fabricated the M rim. gap with a movable planar mirror of 500 urn in diameter. The gap was changed from 825 nm to 1020 nm by applying the voltage of 24 V.

    This paper reports on a flexible micro planar coil for an MR (Magnetic Resonance) catheter. High resolution images can be obtained by using the MR catheter. Two types of coils of 5 mm and 20 mm in diameter were fabricated. Both of the coils were designed to have inductance of 1.0 mu H at 8.5 MHZ. The proto-type MR catheters were made by attaching the micro coils to the tip of acrylic pipes. In order to evaluate the MR catheters, the sensitive area and SNR (Signal to Noise Ratio) were measured. SNRs of the MR catheters were about three to eight times higher than that of a standard medical coil. Furthermore, we demonstrated that high resolution MR images can be achieved by using the MR catheters. MR images of a gumbo (Abelmoschus esculentus) were acquired with 0.5 x 0.5 x 1.0 mm(3) resolution. While clear MR images were not able to be taken by the standard medical coil due to its low SNR, we were able to observe the gumbo and distinguished its seeds one by one in the MR images taken by the MR catheters.

    This paper reports on an optical blood test device using a micro Fabry-Perot interferometer (micro FPI) implanted in a body. Since we intend to measure many kinds of information from blood by using only one device, we have developed a micro FPI. A prototype of the micro FPI was fabricated beforehand to check the characteristics of the micro FPI. The prototype can be used in wide wavelength ranging from visible light to near-infrared. It transmits the light from 30 to 80% in the range. The light transmittances of arterial blood and venous blood were measured by the prototype. Based on the prototype, a micro FPI was fabricated. The characteristics of the micro FPI are similar to the prototype. It turns out that this micro FPI has sufficient characteristics to measure the oxygen concentration.

    In this study, we fabricated micro planar coils as a receiver for a high sensitive MRI (Magnetic Resonance Imaging). According to the calculation of the scale effect, the sensitivity of the coil increases with decrease of the diameter of the coil under the condition of fixed inductance. The micro planar coils of 5 and 20 mm in diameter were fabricated by using MEMS technology. The resistance and inductance of the 20 mm coil were 1.4 Ω and 1.15 μH at 8.5 MHz, respectively. Those of the 5 mm coil were 2.0 Ω and 1.05 μH, respectively. The MRI signal receivers were made by attaching the micro coils to the tip of acrylic pipes. The SNRs (Signal to Noise Ratio) of MR images of phantom were measured by the micro planar coils and the medical MRI coil of 200 mm in diameter. The SNRs of MR images taken by the micro planar coils were about 8 times as high as the MR image taken by the medical coil. MR images of an okra (Abelmoschus esculentus) were acquired by fabricated MRI signal receivers with the voxel size of 2.0 × 2.0 × 2.0 mm3 and 0.5 × 0.5 × 1.0 mm3. Since the sensitivity of micro planar coils was high, we were able to clearly observe inner structure of the okra.

    In this study, we fabricated a wearable blood pressure pulse wave measurement device for daily health care using the arterial tonometry method. The wearable device comprises a MEMS (Micro Electro Mechanical Systems) 3-axis force sensor array, a 3-axis adjustment mechanism, amplifier circuits, a band, and a signal-processing board. The MEMS sensor array could be pressed adequately onto the radial artery by using the 3-axis adjustment mechanism. Then we evaluated the accuracy of blood pressure. The correlation coefficient between the pressure measured by the prototype device and the blood pressure measured by a commercially available manometer was 0.90, and that was increased to 0.99 by using the blood pressure calculated by the regression equation based on the features extracted from the pulse wave. Furthermore, since the correlation coefficient of our wearable device was above 0.95, our wearable device could measure the blood pressure with high accuracy.
