One-Step Manufactured Meta-Bots with Medical Potential

Engineers at the University of California Los Angeles have developed “meta-bots,” which are fingernail sized robots that can move, sense, and navigate their environment. Strikingly, the robots are essentially ready for use when they emerge from the 3D printer, and consist of piezoelectric actuators that can respond to or generate electricity. The robots consist of …

Polymer Brushes Capture and Release Proteins on Demand

Researchers at the Chalmers University of Technology in Sweden have developed a “polymer brush” system that can capture and release proteins on using electrical stimulation. Protein therapeutics are increasingly in demand, but creating them efficiently is still a challenge. Isolating therapeutic proteins from the liquid surrounding the cells used to produce them in biotechnological processes …

AI-Powered Surgical Robot Excels at Tricky Kidney Stone Procedure

Clinical researchers at Nagoya City University in Japan have tested an AI-powered surgical robot in its ability to assist with percutaneous nephrolithotomy, which is a minimally invasive procedure to remove large kidney stones. The technique involves accessing the kidney through the skin, and typically requires a highly experienced surgeon. The robot, called the Automated Needle …

Flexible Microprobe for Neural Interfacing

Researchers at the University of California San Diego have developed a tiny neural probe that is approximately one fifth of the width of a human hair. The probe is flexible and can be implanted for extended periods without aggravating the immune system, in part because of its small and unobtrusive profile. Its miniature size means …

Automated Wearable Breast Ultrasound System: Interview with Maryam Ziaei, CEO of iSono Health

iSono Health, a medtech company based in San Francisco, has created the ATUSA System, a wearable 3D ultrasound breast scanning system. The device is worn on the breast, and does not rely on operator experience or skill to obtain consistent, high quality breast scans. As the scanning takes place automatically, it can be used by …

Self-Regulating Footwear for Diabetic Foot Issues

Researchers at the Indian Institute of Science created footwear that can self-regulate the pressure distribution when a person walks, helping to avoid pain and friction that can lead to issues for people with diabetes. Patients with diabetes can have an abnormal gait, sometimes because of pain or numbness in the extremities, potentially leading to complications …

Living Skin Layer for Robots and Prostheses

Researchers at the University of Tokyo have developed a method to coat a robotic finger in a living “skin” layer. The living coating is strong and flexible enough to allow the robotic finger to bend and flex, and it can repel water and even self-heal if damaged. The technique involves coating the robot in a …

Cuffless Blood Pressure Monitoring: Interview with Jiang Li, CEO at Vivalink

Blood pressure is a crucial factor in cardiovascular health, but measuring it using conventional pressurized cuff systems in a doctor’s clinic is prone to unreliable results. A one-off measurement merely offers a clinician with one snapshot in time, potentially missing an intermittent issue. However, patients can also be prone to “white coat syndrome,” where anxiety …

Lipid Nanodiscs Unlock the Potential of Cytokine Treatment

Researchers at the University of Texas at Austin created a nanocarrier for stem cell factor, a regenerative cytokine. The nanotechnological approach renders the treatment much safer, as previous attempts to use stem cell factor as a pro-angiogenic treatment have been hampered by severe allergic reactions in some recipients. This latest technology helps to unlock the …

Fabric Makes Electricity from Movement to Power Wearables

Scientists at Nanyang Technological University, Singapore, have created a wearable fabric that generates electricity from our body movements. The fabric could assist in powering medical wearables and other mobile diagnostic or therapeutic devices. The fabric contains stretchable polymers that generate electricity when bent, pressed, or brushed, based on piezoelectric and triboelectric effects. The fabric is …
