Sweet Success

Microelectrodes can be used to measure electrical signals within organs such as the brain, but the hard materials microelectrodes are usually made of can cause problems when transplanted into the body. Bernhard Wolfrum and team successfully inkjet-printed microelectrode arrays (MEAs) onto a variety of soft materials, including gummy sweets, in the hope of one day developing better sensors for biomedical applications (1).

About the Author
Joanna Cummings

A former library manager and storyteller, I have wanted to write for magazines since I was six years old, when I used to make my own out of foolscap paper and sellotape and distribute them to my family. Since getting my MSc in Publishing, I’ve worked as a freelance writer and content creator for both digital and print, writing on subjects such as fashion, food, tourism, photography – and the history of Roman toilets. Now I can be found working on The Analytical Scientist, finding the ‘human angle’ to cutting-edge science stories.
