A skin sensor developed at MIT is as thin as adhesive tape and sends signals - without a chip or battery. The device can vibrate in response to a person's heartbeat or the salt in their sweat, as well as generate a readable electrical signal.

Anesthetic drugs affect the brain. But to tell if a patient will remain unconscious during surgery, most anesthesiologists rely on heart rate, breathing rate and movement. Algorithms could improve this process.

Researchers have created a reference database of a blood marker that can be used to measure the disease state of patients with multiple sclerosis. They hope this will open the way to more targeted and personalised therapies.

Engineers at MIT have developed a sweat-proof electronic "skin." The design could lead to adaptable, wearable monitors for monitoring skin cancer and other diseases.
