Creating the Future: Wearable Bands Offer Continuous Blood-Pressure Measurement

The pneumatic cuff, a device traditionally used to measure blood pressure, has had a prominent place in doctors' offices for more than a century. As part of a year-long fellowship at Northwestern University, two clinicians and two engineers teamed up to develop a new way of measuring blood pressure: cuffless, wearable wristbands.

Tool Helps Design Soft Robots That Can Bend and Twist

Designing a soft robot to move organically — to bend like a finger or twist like a wrist — has always been a process of trial and error. Now, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences and the Wyss Institute for Biologically Inspired Engineering have developed a method to automatically design soft actuators based on the desired movement.

Developing a Laser System to Decrease the Rate of Neurodevelopment Issues

A fairly new biomedical imaging modality, optoacoustic imaging is based on the use of laser-generated ultrasound. According to the National Center for Biotechnology Information, it is a hybrid method that has emerged over the past two decades, combining the high-contrast and spectroscopic-based specificity of optical imaging with the high spatial resolution of ultrasound imaging.
