Magnetic control: Micromagnets dispersed in a soft porous system make it magnetoelastic. Compresssing the system shifts the magnets’ positions, changing the overall magnetism. (Courtesy: Nat. Mater.

Parkinson's disease is best treated when detected early, but the cost of those tests makes that difficult. A new, 3D-printed ...

The new pen’s tip is made of small neodymium magnets mixed into Ecoflex, a brand of silicone rubber advertised for production of prosthetics and film props. The body contains a reservoir of ferrofluid ...

The pen finds early signs of Parkinson’s by studying handwriting. It works without batteries and can be used in regular check ...

Chen and his team, who discovered the magnetoelastic effect in soft systems in 2021, also plan to explore new ways to incorporate his findings into other wearable or implantable bioelectronics.

1. Shown is the basic magnetoelastic-effect-based soft system and key attributes that led to the combined magnetoelastic generator and its ability to sense even slight dimensional disturbances.
