Surgical robots could make some types of surgery safer and more effective, but proving that the software controlling these machines works as intended is problematic. So say researchers at Carnegie Mellon University, Pittsburgh, PA, and the Johns Hopkins University Applied Physics Laboratory, Baltimore, MD, who have demonstrated that methods for reliably detecting software bugs and ultimately verifying software safety can successfully be applied to these robots.

Electrocardiogram (ECG or EKG) measurements typically involve time-consuming skin preparation, lead application, conductive gels, and even shaving of body hair. More recently, dry contact sensors have come into use in some sports and home health monitoring units, but these frequently experience contact problems, particularly in users with dry skin.
