A new wearable ultrasound patch that non-invasively monitors blood pressure in arteries deep beneath the skin could help people detect cardiovascular problems earlier on and with greater precision. In tests, the patch performed as well as some clinical methods to measure blood pressure. Applications include real-time, continuous monitoring of blood pressure changes in patients with heart or. Quantifying the contact area during skin-to-skin interactions, and at the same time using it as feedback, would increase the efficiency of clinical care and assist in the development of future medical and service robots with sensing capabilities. Soft and wireless wearable devices in clinical settings offer significant advantages over. to improve the soft robot designs (Shih et al., 2020). Because of the inherent material match and functional complementarity between the skin-like devices and soft robots, there have been significant efforts to develop skin-like stretchable and wearable sensors for integration with soft robotic systems. Biological. Dr Shiming Zhang of the Department of Electrical and Electronic Engineering, who leads the HKU WISE (wearable, intelligent and soft electronics) Research Group to develop the system stated that the team's wearable system is extremely small, soft and imperceptible to wearers, and it can continuously monitor the body condition. We aim to address how humans can have rich interaction with wearable devices and embedded devices with low-cost, low-power, and with real time constraints. In that pursuit, we have primarily focused on capacitive sensing devices and models for interacting with multi-modal sensors. Below are the relevant publications from this research thrust:. Soft Robotic Glove. In the United States, the lifetime risk of developing heart failure is roughly 20%. The current clinical standard treatment is implantation of a ventricular assist device that contacts the patient's blood and is associated with thromboembolic events, hemolysis, immune reactions and infections. Soft fluidic actuators consisting of elastomeric matrices with embedded flexible materials (e.g. cloth, paper, fiber, particles) are of particular interest to the robotics community because they are lightweight, affordable and easily customized to a given application. These actuators can be rapidly fabricated in a multi-step molding process and. A research team has designed a simple. Soft Robotic Glove. In the United States, the lifetime risk of developing heart failure is roughly 20%. The current clinical standard treatment is implantation of a ventricular assist device that contacts the patient's blood and is associated with thromboembolic events, hemolysis, immune reactions and infections. Matti Mantysalo, Tampere University of Technology, et al. will present on printed soft-electronics for remote body monitoring, including fabrication and characterization of electrode bandages and temperature sensors (10366-13).Among wearable electronics entering consumer markets over the past few years, wrist devices and textile integration are common technologies for unobtrusive measuring. An integrated iontophoresis module on a wearable sweat sensor could enable autonomous and programmed sweat extraction. A microfluidics-based sensing system was demonstrated for sweat sampling, sensing, and sweat rate analysis. Roll-to-roll gravure printing allows for mass production of high-performance flexible chemical sensors at low cost. Acceptance Notification of Full-Length and SS Papers - July 19, 2022.

Our approach, termed soft tubular microfluidics, provides a simple, cheaper, and faster solution for users lacking pro-ficiency and access to cleanroom facilities to design and rapidly con-struct microfluidic devices for their various applications and needs. During a talk at the Smart Fabrics Virtual Summit in 2019, Brad Holschuch, assistant professor of wearable technology and apparel design at the University of Minnesota College of Design, discussed the potential innovation at the intersection of wearables and soft robotics. Holschuch noted that when applied to applications with shape memory. Secondly, reliably fixing soft electronic devices on organs that are moving or pulsating has so far proved to be highly challenging.

However, changes in tissue mechanical properties deep inside the tissue are difficult for human operators to sense, because the relatively large friction force between the needle shaft and the surrounding tissue masks the smaller tip forces. A novel robotic coaxial needle insertion assistant, which enhances operator force perception, is presented. The new ultrasound patch can continuously monitor central blood pressure in major arteries as deep as four centimeters (more than one inch) below the skin. When worn on the neck, the device records central blood pressure in the carotid artery (CA), internal jugular vein (Int JV) and external jugular vein (Ext JV). (Image: Chonghe Wang).
