Wearable lung-health monitoring system with electrical impedance tomography.

The wearable lung-health monitoring system is proposed with an electrical impedance tomography (EIT). The proposed system has light belt-type form factor which is implemented with the EIT integrated circuit (IC) on the planar-fashionable circuit board (P-FCB) technology. The EIT IC provides programmable current stimulation which is optimally controlled by the results of contact impedance monitoring.

A 259.6 μW HRV-EEG Processor With Nonlinear Chaotic Analysis During Mental Tasks.

A system-on-chip (SoC) with nonlinear chaotic analysis (NCA) is presented for mental task monitoring. The proposed processor treats both heart rate variability (HRV) and electroencephalography (EEG). An independent component analysis (ICA) accelerator decreases the error of HRV extraction from 5.

Wearable depression monitoring system with heart-rate variability.

A wearable depression monitoring system is proposed with an application-specific system-on-chip (SoC) solution. The SoC is designed to accelerate the filtering and feature extraction of heart-rate variability (HRV) from the electrocardiogram (ECG). Thanks to the SoC solution and planar-fashionable circuit board (P-FCB), the monitoring system becomes a low-power wearable system.

A sub-10 nA DC-balanced adaptive stimulator IC with multi-modal sensor for compact electro-acupuncture stimulation.

A compact electro-acupuncture (EA) system is proposed for a multi-modal feedback EA treatment. It is composed of a needle, a compact EA patch, and an interconnecting conductive thread. The 3 cm diameter compact EA patch is implemented with an adaptive stimulator IC and a small coin battery on the planar-fashionable circuit board (P-FCB) technology.

The Smart Patches and Wearable Band (W-Band) for comfortable sleep monitoring system.

The Smart Patches and Wearable Band (W-Band) are proposed for comfortable sleep monitoring system which recognizes and diagnoses sleep disorders. By using Planar Fashionable Circuit Board (P-FCB) techniques, the Smart Patches are implemented with the plain fabric patch so that it can have light weight and small size. And the stretchability of the W-Band can achieve user convenience, low manufacturing cost, and low power consumption all at once.

Changes in the activity of the multifunctional beta-glycosyl hydrolase (Cel44C-Man26A) from Paenibacillus polymyxa by removal of the C-terminal region to minimum size.

Paenibacillus polymyxa GS01 secretes Cel44C-Man26A as a multifunctional enzyme with cellulase, xylanase, lichenase, and mannanase activities. Cel44C-Man26A consists of 1,352 amino acids in which present a catalytic domain (CD) of the glycosyl hydrolase family 44 (GH44), fibronectin domain type 3 (Fn3), catalytic domain of glycosyl hydrolase family 26 (GH26), and a cellulose-binding module type 3 (CBM3). A truncated Cel44C-Man26A protein, consisting of 549 amino acid residues, reacted as a multifunctional mature enzyme despite the absence of the 10 amino acids containing GH44, Fn3, GH26, and CBM3.

Construction of the bifunctional enzyme cellulase-beta-glucosidase from the hyperthermophilic bacterium Thermotoga maritima.

An artificial bifunctional enzyme, cellulase-beta-glucosidase, was prepared by gene fusion from the hyperthermophilic bacterium Thermotoga maritima MSB8. The fusion protein exhibited both cellulase (Cel5C) and beta-glucosidase (BglB) activity when the bglB gene was fused to downstream of cel5C, but not when cel5C was fused to downstream of bglB. The specific activity of the bifunctional enzyme was 70% lower than that of cellulase or beta-glucosidase.
