Failure is not an option when it comes to medical equipment. From critical or sensitive devices like lasers, MRI scanners, knee joints, and implantable pacemakers to instruments as straightforward as stethoscopes, when life is at stake, medical equipment must be reliable.

Brain-machine interfaces could someday be used routinely to help paralyzed patients and amputees control prosthetic limbs with just their thoughts. Now, University of Florida researchers have devised a way for computerized devices not only to translate brain signals into movement, but also to evolve with the brain as it...

A tiny sensor that can detect magnetic field changes as small as 70 Femtoteslas — equivalent to the brain waves of a person daydreaming — has been demonstrated at the National Institute of Standards and Technology (NIST). The sensor could operate on a single AA battery and reduce the costs of non-invasive biomagnetic...

For an estimated 10 million people worldwide who are blind due to cornea damage or disease, there may be hope in the form of an innovative artificial cornea design that reportedly overcomes the limitations of existing artificial corneas. Existing cornea implants need to be made larger to prevent excess corneal tissue from growing...
