A Better Camera Pill

1 min read

A collaboration of engineers led by the Fraunhofer Institute for Biomedical Engineering, in St. Ingbert, Germany, has developed the first-ever control ­system for a camera pill. Natural motions propel today’s camera pills through the esophagus too fast to take all the ­pictures that doctors would like to see. The Fraunhofer pill is steered using an ­external magnet held by a physician. ”In the future, doctors will be able to stop the camera in the esophagus, move it up and down, and turn it,” says Frank Volke, a researcher at Fraunhofer.

A New Treatment for Arthritis: Vagus-Nerve Stimulation

Studies will soon show whether electroceuticals outperform pharmaceuticals

Monique Robroek once had such crippling arthritis that, even with the best available medications, she struggled to walk across a room. But thanks to an electronic implant fitted under her skin, she managed to wean herself off all her drugs and live pain-free for nearly a decade—until recently, when a viral illness made her rheumatoid arthritis (RA) flare up again.

This article is part of our special report Top Tech 2023.

Robroek’s long remission is “very impressive” and rare among patients with RA, says her doctor Frieda Koopman, a rheumatologist at Amsterdam UMC, in the Netherlands. Robroek’s experience highlights the immense potential of so-called bioelectronic medicine, also known as electroceuticals, an emerging field of treatment for diseases that have traditionally been managed with pharmaceuticals alone.
