Personal thermal management represents a new paradigm to reduce the energy consumption, which consists in controlling the temperature around the human body rather than regulating the temperature of the entire residential space. Recent progress in smart textile showed promising radiative heating and cooling performance. However, propositions for double functional textiles, namely cooling and heating, are still limited. We present here a theoretical study of a dynamic thermoregulatory fabric (DTF) able to regulate the human body temperature by adapting its geometry. The DTF is a 2D photonic crystal constituted of an ultra-thin metallic film sandwiched between two temperature-sensitive polymer membranes. The stacked geometry is drilled with air holes according to a triangular array. We demonstrate that the DTF is able to maintain the thermal comfort over a wide range of room’s temperature by dynamically controlling the mid infrared (MIR) radiations of the human body.

Although one-dimensional anodic TiO2 nanotube arrays (TNTs) have attracted considerable attention in various fields due to their remarkable functionalities, their poor electrical conductivity limits their practical applications. Here, we present a simple approach of electrochemical silver doping of TNTs electrodes that significantly improves electronic conductivity and electrocatalytic performance towards electrochemical sensing. Glucose was chosen as an analyte to investigate the electrocatalytic sensing properties of Ag doped TNTs, and various analysis such as cyclic voltammetry, sensitivity, chronoamperometry, and electrochemical impedance spectroscopy (EIS) were performed using a three-electrode system. The Ag doped TNTs showed nearly 50 times higher sensitivity (from 0.4 µA mM-1 cm-2 to 21 µA mM-1 cm-2), lesser detection limit (from 0.52 mM to 0.07 mM), less charge transfer resistance (from 3.63 Ω to 2.35 Ω), and reduced bandgap (from 3.2 eV to 3 eV) as compared to plain TNTs. The enhanced response of Ag doped sensors was attributed to the reduced bandgap that induced defect states and increased electron transfer rate required for oxidation of glucose. Perspective wise, the synthesis of Ag doped TNTs through a single electrochemical anodization step can be a faster and a promising technique that is highly desirable for enhancing the performances of nanomaterial-based electrochemical sensors.

Industrial robotic arms are used extensively in sectors including manufacturing, healthcare, and infrastructure. Electrical current sensors located in the joints of industrial robots are critical for maintaining safe and optimal performance. However, the current sensors are subject to inaccuracies resulting from performance degradation, which results in safety hazards and sub-optimal performance. Thus, this research describes, develops, and experimentally validates an external load-based sensing system and methodology to detect unacceptable drift of current sensors in industrial robots. The initial states of the current sensors are recorded using low-cost load cells mounted on each joint of a UR10 robot. Thus, subsequent current sensor measurements can be compared to the initial state to determine statistically significant current degradation. This paper demonstrates the load-based sensing system is subject to less variability compared to current sensor verification under free loading conditions, and further analysis shows the load cells can be selectively mounted onto specific joints. In addition, a case study shows that the external load-based system can robustly detect simulated current sensor degradation. Thus, this sensing system is an efficient, robust, and cost-effective method towards detecting electrical current degradation in industrial robots.

High sensitivity MEMS pressure sensor chip for different ranges (1 to 60 kPa) utilizing the novel electrical circuit of piezosensitive differential amplifier with negative feedback loop (PDA-NFL) is developed. Pressure sensor chip PDA-NFL utilizes two bipolar-junction transistors (BJT) with vertical n-p-n type structure (V-NPN) and eight piezoresistors (p-type). Both theoretical model of sensor response to pressure and temperature and experimental data are presented. Data confirms the applicability of theoretical model. Introduction of the amplifier allows for decreasing chip size while keeping the same sensitivity as a chip with classic Wheatstone bridge circuit.

A new method for the implementation of a fluid-independent thermal flowmeter is presented, combining the 3ω-method and constant temperature anemometry. It is shown that a single calibration with a reference fluid (water in this case) leads to a high accuracy (< 4%). The measurement method was verified for water, isopropanol, and an isopropanol-water mixture. The deviation between measured flow rate value and reference flow rate value is less than 4% with respect to the full scale value. The findings may play a key role for next generation thermal flow meters.

Epidermal stimuli induced by human physiology and human motion, such as skin surface flow, mechanical strain, and temperature, provide valuable information for health and physiological monitoring. Here, we propose a multifunctional stretchable sensor based on thermosensation, enabling multi-sensations of flow, strain and temperature. We develop a simple and low-cost ink printing technique using homemade Ag-Ecoflex composite ink to fabricate thermosensitive ribbons on Ecoflex substrate to form the stretchable sensor. Low cross-coupling among multiple sensations is implemented by using scheme of concentric annular thermosensitive ribbons, constant temperature difference (CTD) circuit and adaptive filter. The stretchable sensor possesses merits of high integration, simple fabrication and low cost. The sensor has promising potentials in applications of wearable healthcare and human motion monitoring.

This paper develops an ultra-low power single-chip voice interface consisting of a programmable gain amplifier (PGA) and 12-bit asynchronous successive-approximation register analog-to-digital converter for MEMS microphone sensor. The PGA’s current can be scaled down from 100uA to 10uA and the measured SNR in 94dBSPL(14mV) is 74dB and 67dB, respectively. It can also set a programmable gain of 40/34/31/28dB for specific demands of microphone. Total Harmonic Distortion (THD) is measured at different output amplitudes, the design exhibits lower than 0.25% THD+N with 94 dBSPL(14mV) at 1kHz. The SAR ADC operates with an 8-kHz sampling rate and consumes only 400nW from a 1.2V VDD. The measured signal-to-noise and distortion ratio (SNDR) is 67.46 dB and spurious-free dynamic range (SFDR) is 87.97 dB. Its sampling rate can be easily scaled from 1M-S/s to 1S/s with a linear power scaling feature. The proposed circuit realized in 180nm CMOS process demonstrates a successful voice data processing (speech/voice recognition, presentation) with the MEMS sensor and an off-chip platform.

To increase the productivity of agricultural crops, a growth method based on the physiological information of plants is required. In recent years, there is an increased demand for methods of minimally invasively measuring physiological information from plants. In this study, we propose a novel single-probe heat-pulse microsensor for minimally invasive measurement of water transportation (sap flow velocity) in plant shoots based on the fundamental conduction–convection principles of heat transport. The proposed sensor comprises a resistance temperature detector and a filament heater on a probe. We verified the performance of the sensor using thermal analysis and fabricated a sensor using microelectromechanical system technology. Finally, we demonstrated the feasibility of minimally invasive measurement of water transportation (measurement range: approximately 0–4 mm/s) in plant shoots.

In this work, we study the effect of transistor downscaling in a wireless communication circuit for Body Dust application. The system requires a chip lateral size smaller than 10 µm miming the typical size of a red blood cell and so, supporting free circulation in human tissues. Moreover, an ultralow-power architecture is needed since the system is battery-less and wirelessly powered via acoustic power transfer. The aim of this paper is to present a data communication system for Body Dust systems, which works from the multiplexed sensor read-out front-end to the transmitter back-end taking account diagnostic information on different metabolite concentrations in human body. This work shows that scaling the architecture from a 0.18-µm to 28-nm CMOS processes, it is possible to improve both size and power consumption. The improvement is about 40 times in size (2000 µm2 down to 50 µm2) and two order of magnitude in average power consumption (10 µW to cents of nW).

We formulated an alcoholic-based ketjen black ink to construct conductive layer. In addition, molecularly imprinted sol-gels ink was synthesized to realize specific selectivity. To obtain best sensor performance, the main two parameters, template concentration and crosslinker/monomer ratio, were optimized.
