Fully casted wearable soft triboelectric devices for energy harvesting and motion sensing are presented. Developed devices feature simple designs and are made of elastomeric materials where scalable fabrication methods can be applied. Film casting and stencil printing techniques were used to deposit polydimethylsiloxane (PDMS), polyurethane (PU) and carbon-based elastomeric materials. The soft triboelectric generator (TENG) with sliding design provides a higher output density of 3.6 μW/cm2 in comparison to 0.05 μW/cm2 for the vertical mode design, at operational frequency of 0.9±0.2 Hz. These soft TENGs demonstrated sensing and energy scavenging capabilities from body movements.

We report on the integration of a dielectric elastomer actuator (DEA) operating at 1 kV with a flexible metal oxide high-voltage thin film transistor (HVTFT). With only a 30 V gate voltage, the HVTFT controls the kV voltage drop across the DEA, thus providing low-voltage control over the DEA actuation. Both the DEA and the HVTFT are stable up to over 105 cycles. This integrated DEA+HVTFT actuation strategy represents a key building block for smart complex compliant machines, for which multiple independent soft actuators are required. An array of many such building blocks can be driven by a single DC kV power supply, with each DEA individually addressed with low-voltage signal outputs, for example in a row/column architecture. Since the switching logic now operates at low voltage, one can integrate high-level control in multi degree of freedom soft DEA robots.

The study of wearable devices has become a popular research topic recently, where high-sensitivity, noise proof sensing mechanisms with long-term wearability play critical roles in a real-world implementation. Here, we introduced a flexible supercapacitive sensing modality to all-fabric materials for wearable pressure and force sensing using an elastic ionic-electronic interface. Notably, an electrospun ionic fabric utilizing nanofibrous structures offers an extraordinarily high pressure-to-capacitance sensitivity (114 nF·kPa−1), which is at least 1,000 times higher than any existing capacitive sensors and one order of magnitude higher than the previously reported ionic devices, with a pressure resolution of 2.4 Pa, achieving high levels of noise immunity and signal stability for wearable applications.

This paper describes a highly pure phloem-sap-extraction sensor device that mounts a phloem position-identification sensor. Convenient methods of artificially extracting highly pure phloem sap for quantitative analysis of plant nutrition have yet to be established. To realize direct analysis of nutrition as well as long-term monitoring of its component fluctuation, we propose a novel sensor device that can distinguish phloem and xylem positions stably for a long time and extract only pure phloem sap.

This paper presents a simple optoelectrokinetic method for manipulating particles by simultaneously inducing electrohydrodnamic flow and electrokinetic motion. With carefully tuning the balance between several forces acting on particles, multiple manipulation capabilities including aggregation, translation, sorting, and patterning were achieved. In combination with bead-based immunoassays, we successfully performed fluorescent signal enhancement for a dilute analyte (∼10 pg/mL), tumor necrosis factor-alpha (TNF-α), and achieved a proof of concept for simultaneous detection of dual biomarkers. The development of such a technique can provide insight to diagnosing diseases in the early stage.

We have successfully fabricated and installed flexible magnetic tag which has about 9 bits information to biological material in limited space under wet environment. The magnetizing of tag use focusing of magnetic field based on the magnetic circuit using high magnetic permeability material. Fundamental test for the magnetic tag show the magnetic signal can be discriminated even 30 days after injection of magnetic tag. This study can contribute to identify the various gene transferred biomaterials and contribute to the gene technology and long-term monitoring of environment.

This paper describes a stimuli-responsive microfiber-bundle actuator that has hierarchical alignment from molecular scale to macroscopic scale. We succeeded in aligning the orientation of molecular scale polymer chains in the stimuli-responsive hydrogel microfiber, which enhances the shrinkage of axial direction of the microfiber. We also bundled the microfibers and constructed a macro-scale bundled microfiber. The actuation of the bundled microfiber was confirmed by stimulating with temperature. We believe that this approach could enhance the performance of functional polymer materials for applications such as biomimetic actuators and soft robots.

This paper reports a new integrated microfluidic platform capable of automating two kinds of on-chip tissue slide-based in-vitro screening processes, including a systematic evolution of ligands by exponential enrichment (SELEX) process and a phage display screening process. Tissue slide is one of the most important biopsy samples for cancer patients in clinical diagnosis. It is the first time that a solid biopsy (tissue slide) was used on an integrated microfluidic system for screening of two kinds of affinity reagents, including aptamers (nucleic acids type) and peptides (amino acids type). The screened aptamers and peptides have been tested with high affinity and specificity toward target cancer

We propose the synergic operation of two devices that consist of a high quality sperm sorter and an oocytes zona-removal as well as incubation device for promoting the successful rate and the efficiency of In-vitro fertilization (IVF). The high quality sperm sorter can gently sort out large number of sperms in few minutes and keep high survival rate for oligospermia patients. The oocytes zona-removal and incubation device can rapidly reduce enzyme contraction after gently removing oocytes shell. Experiment results showed that these two devices not only provide an easier and faster method to sort out motile sperms as well as better preserve the viability of dezona oocytes, but also increase the attachment rate of sperms on oocytes for enhancing fertilization.
