This study investigates the effects of two different catalytic activation techniques on the thermal performance of the flip-chip heat spreaders. The two activation techniques studied are thin nickel–copper strike and galvanic initiation. Thermal diffusivity and surface roughness of these heat spreaders were studied using the Nano-flash Apparatus and Infinite Focus Microscopy. High temperature s...

Recent advances in biomedical sensors, data acquisition techniques, microelectronics and wireless communication systems opened up the use of wearable technology for ehealth monitoring. We introduce a galvanic coupled intrabody communication for monitoring human body hydration. Studies in hydration provide the information necessary for understanding the desired fluid levels for optimal performan...

the objective of this study was to describe the role of electrical stimulation in controlling peripheral vertigo. in a prospective study on 13 healthy volunteers, nystagmus was induced with caloric stimulation and the interval of nystagmus disappearance was recorded. this time indicates the basal response of vestibular end-organ. after caloric irrigation, pulsed signal was applied for each pers...

introduction to extract and combine information from different modalities, fusion techniques are commonly applied to promote system performance. in this study, we aimed to examine the effectiveness of fusion techniques in emotion recognition. materials and methods electrocardiogram (ecg) and galvanic skin responses (gsr) of 11 healthy female students (mean age: 22.73±1.68 years) were collected ...

A first 352 Mhz CH-cavity is under construction, which will demonstrate main production steps like stem welding and galvanic copper palting of the completed stainless steel tank module

The objective for this study was to investigate whether the postural control adaptation during galvanic stimulation of the vestibular nerve were similar to that found during vibration stimulation to the calf muscles. A method for adaptation analysis was used to analyze the evoked changes of posture, stimulus responses and the motion dynamics. The adaptive adjustments of postural control were si...

Microswimmers are small particles capable of converting available energy sources into propulsion owing to their compositional asymmetry, and promising for applications ranging from targeted delivery enhanced mixing at the microscale. However, current fabrication techniques demonstrate limited scalability and/or rely on excessive use expensive precursor materials. Here, a scalable Pickering-wax ...
