Researchers at Johns Hopkins Medicine (Baltimore,MD,USA;www.hopkinsmedicine.org) have designed a wrist-worn sensor device that vibrates proportionately to the pressure exerted on the tissue during surgical training scenarios.

The more force applied,the stronger the resulting vibration.Although devices like this might initially slow the learning process as users adapt to the feedback,the researchers anticipate that it will ultimately enhance the overall training process.

The next stage of the study will explore how effectively using this device can contribute to improved surgical performance and patient safety.
