Special Issue Information

Dear Colleagues,

Force sensors are undergoing tremendous growth these days, and intensive research is being performed in academia or Industrial circles. Mechanical force sensors play key roles in fundamental measurements and practical applications, such as force (tensile/compression) or pressure sensors, accelerometers, and inertial sensors or seismometers. Sensitivity is one of the essential factors of mechanical force sensors. Although various schemes of sensors have been developed with improved sensitivities, for example, the atomic force microscope (AFM)-based force sensor which shows ultrahigh sensitivity with various schemes including nonlinear dynamics, there still exists much demand for novel devices that use the unexplored mechanical mechanisms or scheme to address this issue.

The aim of this Special issue on “Development and Applications of the Sensitive Mechanical Force Sensors” is to bring together and specify the various techniques (development and applications) of force sensors as a viewpoint of sensitivity increment with following themes.

  • Linear/nonlinear mechanical sensors;
  • Quantitative sensitive mechanical sensors;
  • Atomic force microscope-based sensitive force sensors;
  • Bio-mimetic sensitive sensors;
  • Development and applications of force sensors in various environments, such as aerospace/automobile engineering, energy and environmental technology, oil and gas, medical/pharmaceutical industry, paper and cellulose industry, food and beverage industry.

This paper reports on a force plate (FP) using mechanical springs and noncontact distance sensors. The ground reaction force (GRF) is one of the factors for clarify biomechanics, and FPs are widely used to measure it. The sensor elements of conventional FPs are mainly strain gauges. Thus, the mechanical properties of FP depend on the sensor element performance. If the FP performance must change, we must redesign the FP, including changing the sensor elements. Here, we proposed an FP that uses a measuring principle based on simple springs and noncontact sensors. The shape and performance of the proposed FP are expected to change easily. As a prototype device, we designed and fabricated an FP installed with 12 springs and four sensors for human walking. A planar coil and magnet were used as the sensor elements, and the sensor output was proportional to the vertical and horizontal displacements. The FP resonance frequency was 123 Hz, which was larger than the required specification. The calibration experiments showed that vertical and horizontal forces and moments could be measured independently. The FP’s resolutions were 1.9 N and 1.4 N in the anterior–posterior and vertical directions, respectively. Furthermore, the fabricated FP measured GRF similarly to the commercial FP when a human walked on the plate. These results suggest that the proposed method will be helpful for FPs with custom-made requirements. Full article

Strain gage type six-axis force/moment (F/M) sensors have been largely studied and implemented in industrial applications by using an external data acquisition board (DAQ). The use of external DAQs will ill-affect accuracy and crosstalk due to the possibility of voltage drop through the wire length. The most recent research incorporated DAQ within a relatively small F/M sensor, but only for sensors of the capacitance and optical types. This research establishes the integration of a high-efficiency DAQ on six-axis F/M sensor with a revolutionary arrangement of 32 strain gages. The updated structural design was optimized using the sequential quadratic programming method and validated using Finite Element Analysis (FEA). A new, integrated DAQ system was designed, tested, and compared to commercial DAQ systems. The proposed six-axis F/M sensor was examined with the calibrated jig. The results show that the measurement error and crosstalk have been significantly reduced to 1.15% and 0.68%, respectively, the best published combination at this moment. Full article

The aim of the study was to determine the correlation between the mechanical resistance of iris seed capsules and seeds to Mononychus punctumalbum foraging. The principal component analysis (PCA) demonstrated that the first main component referred to the variety type in 68%, and the second main component described the stage of the ontogenetic development of the plant in 26%. As indicated by the values of each parameter measured, all the parameters were found to exert a strong impact on the variability of the analyzed system. The occurrence of weevil infestation was also strongly but negatively correlated with seed wall thickness and capsule wall thickness. There was a correlation of seed max load and seed mass with the occurrence of the weevil. The analysis of the mechanical resistance of iris seed capsules (in June 9.28 N and September 6.27 N for I. sibirica and in June 6.59 N and September 2.94 N for I. aphylla) and seeds (in June 15.97 N and September 344.90 N for I. sibirica and in June 16.60 N and September 174.46 N for I. aphylla) showed significant differences between the terms and species. The PCA analysis revealed that the first variable was correlated with the occurrence of weevil foraging. Full article
