This paper presents a portable, fast and accurate electrochemical impedance spectroscopy (EIS) device with 8-well interdigitated electrode chips for biomarker detection. The design adopts low crest factor multisine signal synthesis at frequencies (<1 kHz) single-tone signals high (>1 kHz), which significantly increases measurement speed without sacrificing accuracy. In addition, the excitation amplitude of 10 mV preserves linearity protects biosamples. system achieved an average magnitude...
Abstract Electrochemical impedance spectroscopy (EIS) has been used in various applications, such as metal corrosion monitoring. However, many conventional monitoring setups are bulky and inconvenient for in-situ testing. The purpose of this work is to reduce the size whole system. We utilized EIS design a field deployable impedance-based sensor (FDICS), capable performing analysis. Experiments verified sensor’s accuracy, results showed that performed similarly bench-top machine when we...
Currently, there is no suitable solution for the point-of-care diagnosis of knee injuries. A potential portable and low-cost technique accessing monitoring injuries bioimpedance measurement. This study validated feasibility bipolar electrode configuration measurement with two electrodes placed on a fixed pair acupuncture locations called Xiyan. Then, collected 76 valid samples to investigate relationship between injuries, among whom 39 patients have unilateral 37 individuals healthy knees....
Introduction: To evaluate whether both acute and chronic low-intensity pulsed ultrasound (LIPUS) affect brain functions of healthy male female mice. Methods: Ultrasound (frequency: 1.5 MHz; pulse: 1.0 kHz; spatial average temporal (SATA) intensity: 25 mW/cm 2 ; pulse duty cycle: 20%) was applied at mouse head in test for 20 minutes, experiment consecutive 10 days, respectively. Behaviors were then evaluated. Results: Both LIPUS exposure did not the abilities movements, mating, social...
In this study, we examined the relationship between sensitivity of interdigitated electrode (IDE) impedimetric biosensors and gap IDEs. Our aim is to find an optimal design maximize sensitivity. A three-dimensional COMSOL model was constructed for determining effects gap, width, height on impedance sensitivity, revealing a singular linear correlation with inner gap. Considering both simulation results fabrication processes, have developed three IDE prototype chips gaps 3 μm, 4 5...

Low-intensity pulsed ultrasound (LIPUS) is a non-invasive medical therapy that has attracted recent research interest due to its therapeutic effects. However, most LIPUS driver systems currently available are large and expensive. We have proposed interface application-specific integrated circuit (ASIC) for use in wearable devices address some of the challenges related size cost current technologies. The ASIC highly system, incorporating DCDC module based on charge pump architecture, high...
By 2050, countries around the world are expected to be gradually phasing out fossil fuels and implementing greener energy technologies. In this work, we present a system employing Energy harvesting, self-powered technology that can recycle from surrounding environment. A high-efficiency radio frequency (RF) energy–harvesting chip was designed fabricated. With an off-chip antenna rectifier, scavenges ambient RF converts it into usable energy, which is then stored in storage elements (such as...
Introduction Low-intensity pulsed ultrasound (LIPUS) is a recognized tool for promoting nerve regeneration and repair; however, the intracellular mechanisms of LIPUS stimulation remain underexplored. Method The present study delves into effects varying parameters, namely duty cycle, spatial average-temporal average (SATA) intensity, amplitude, on therapeutic efficacy using SK-N-SH cells cultured in serum-starved conditions. Four distinct settings were employed: (A) 50 mW/cm 2 , 40%, (B) 25...
