Videos of the Month Smart Knee Brace May Help Prevent or Delay Joint Decline SUTD researchers have developed a smart knee brace that can wirelessly sense joint motion. Made from a single fabric, this stretchable wearable is integrated with a fully functional sensing circuit, off ering continuous monitoring in real time. Graphene Improves Flexible and Wearable Electronics At 200 times stronger than steel, graphene has been hailed as a super material of the future since its discovery in 2004. The ultrathin carbon material is an incredibly strong electrical and thermal conductor. Here, researchers demonstrate that graphene can greatly improve electrical circuits required for wearable and fl exible electronics. Using Chiral Spectroscopy to Enhance Quality Control in Drugs The Kotov Lab at the University of Michigan is working to evade the devastating eff ects of unsafe drugs with a new method of drug screening and quality control. The researchers hope that the technique could also help diagnose harmful accumulations of twisted molecules in the body, including bladder stones, insulin fi brils and amyloid aggregations such as the plaques that appear in Alzheimer's disease. Take a Deep Breath: A Robot Checks for Blood Pressure A robot from Simon Fraser University is learning one of the most familiar tasks at the doctor's offi ce: Taking your blood pressure. The LIO sensors integrated onto the robot's fi ngertips can be positioned on the patient's chest. Blood pressure is monitored and estimated by combining data from ECG and PPG readings, as recorded by sensors on the fi ngers of each hand respectively. 6 www.medicaldesignbriefs.com Medical Design Briefs, September 2023 REDPIXEL.PL/Shutterstock.comhttp://www.REDPIXEL.PL/Shutterstock.com http://www.medicaldesignbriefs.com
