The pupil of the eye allows light to reach the retina, and a number of vision disorders are related to irregularities in the iris that surrounds the pupil. People with aniridia, for example, have some or all of the iris missing, exhibiting a large pupil that results in unfocused vision. Now, a collaboration between Imec, a Belgian research institution, Ghent University, Spain’s Instituto de Investigación Sanitaria Fundación Jiménez Díaz, and Holst Center in The Netherlands, has led to the development…

Robotic surgical assistants, such as the da Vinci systems from Intuitive Surgical, are now routinely used during laparoscopic procedures to improve operative precision, flexibility, and to manipulate multiple tools at once. Such devices can be quite complex inside and so they tend to be quite large, often taking up much of the space of an operating room. Moreover, they are still too cumbersome to operate on particularly fragile tissues and smaller anatomical structures. Now, a pair of researchers from Harvard’s…

Researchers at Purdue University have developed a wearable device that can administer antibacterial ozone gas to chronic wounds to help disinfect them. The technology could allow people to disinfect chronic wounds at home and would be helpful in cases where wounds have been colonized by drug-resistant bacteria and aren’t responding to antibiotic therapy. Approximately 6 million patients in the US have a chronic wound. This includes many patients with diabetes who develop foot ulcers. These wounds can have a significant…

Scientists at the RMIT University in Melbourne, Australia have announced the development of an artificial skin material that can sense pain, temperature, and pressure. It’s remarkable because it replicates how real skin responds to stimuli, which sends appropriate electric signals through neural pathways to the brain. The technology is slated to allow for life-like transmission of tactile sensations through prosthetic arms and legs, and may even help replace skin grafts with artificial solutions. According to RMIT, the electronic skin ‘replicates’…
