Magnetic biomedical devices can pop into shape as needed

April 24, 2023  |  What's New?

One of the challenges of minimally invasive laparoscopic surgery lies in getting surgical instruments into the patient's body via a narrow catheter. Scientists have set about addressing that problem with magnetic instruments that pop into and out of shape as needed. The experimental MaSoChain (magne…

New polymers could enable better wearable devices

April 24, 2023  |  What's New?

Certain electronics that integrate with the human body—a smartwatch that samples your sweat, for instance—work by converting the ion-based signals of biological tissue into the electron-based signals used in transistors. But the materials in these devices are often designed to maximize ion uptak…

MIT engineers design a soft, implantable ventilator

February 27, 2023  |  What's New?

The act of breathing comes naturally, but “behind the scenes,” the diaphragm—the dome-shaped muscle that lies just beneath the ribcage—automatically controls our lung capacity and is the major muscle responsible for our ability to breathe. When the diaphragm’s function is compromised, the …
