IEEE Spectrum’s hottest biomedical tales of the final yr centered each on incorporating new applied sciences and revamping outdated ones. Whereas AI is all the fad in most sectors—together with biomed, with functions like an in-brain warning system for worsening mental health and a mannequin to estimate heart rate in actual time—biomedical information this previous yr has additionally targeted on legacy applied sciences. Tech like Wi-Fi, ultrasound, and lasers have all made comebacks or discovered new makes use of in 2025.
Whether or not innovation stems from new tech or outdated, IEEE Spectrum will proceed to cowl it rigorously in 2026.

When Patricio Riva Posse, a psychiatrist at Emory College College of Drugs, realized that his affected person’s brain implants had been sending him indicators about her worsening despair earlier than she even acknowledged something was improper, he wished he may have taken motion sooner.
That have led him and colleagues to develop “an automated alarm system” for indicators of fixing psychological well being. The instrument screens mind indicators in actual time, utilizing implants to file electrical impulses, and AI to research the outputs and flag warning indicators of relapse. Different analysis teams throughout the United States are experimenting with alternative ways to make use of these stimulating mind implants to assist deal with despair, each with and with out the assistance of AI. “There are such a lot of levers we will press right here,” neurosurgeon Nir Lipsman says within the article.

In Dmitry Kireev’s lab on the College of Massachusetts Amherst, researchers are creating imperceptibly skinny graphene tattoos able to monitoring your vital signs and extra. “Digital tattoos may assist individuals monitor complicated medical circumstances, together with cardiovascular, metabolic, immune system, and neurodegenerative ailments. Almost half of U.S. adults could also be within the early levels of a number of of those problems proper now, though they don’t but comprehend it,” he wrote in an article for IEEE Spectrum.
How does it work? Graphene is conductive, robust, and versatile, in a position to measure options like coronary heart fee and the presence of sure compounds in sweat. For now, the tattoos must be plugged into a daily digital circuit, however Kireev hopes that they may quickly be built-in into smartwatches, and thus less complicated to put on.

Wi-Fi can do extra than simply get you related to the web—it could assist monitor your coronary heart inexpensively and with out requiring fixed bodily contact. The brand new strategy, referred to as Pulse-Fi, makes use of an AI mannequin to research heartbeats to estimate coronary heart fee in actual time from as much as 10 ft away.
The system is low price, totaling round US $40, simple to deploy, and doesn’t introduce discomfort. It additionally works whatever the person’s posture and in all types of environments. Katia Obraczka, a pc scientist on the College of California, Santa Cruz who led the event of Pulse-Fi, says the group plans to commercialize the know-how.

Sangeeta S. Chavan and Stavros Zanos, biomedical researchers on the Institute of Bioelectronic Medicine in New York, hypothesize that ultrasound waves might activate neurons, providing “a exact and protected manner to offer therapeutic therapies for a variety of each acute and continual maladies,” as they write in an article for Spectrum. Focused ultrasound may then function a therapy for irritation or diabetes, as a substitute of medicine with wide-ranging unwanted side effects, they are saying.
It really works by vibrating a neuron’s membrane and “opening channels that enable ions to move into the cell, thus not directly altering the cell’s voltage and inflicting it to fireside,” they write. The authors assume that activating particular neurons may help handle the foundation causes of particular sicknesses.

If a health care provider needs to see inside your head, they must resolve whether or not they need to achieve this cheaply or deeply—an electroencephalograph is cheap, however doesn’t penetrate previous the outer layers of the mind, whereas functional magnetic resonance imaging (fMRI) is dear, however can see all the way in which in. Shining a laser by an individual’s head looks as if step one in direction of know-how that accomplishes each.
For a few years, this sort of work has appeared inconceivable as a result of the human head is so good at blocking gentle, however researchers have now confirmed that lasers can ship photons all over. “What was thought inconceivable, we’ve proven to be attainable. And hopefully…that might encourage the following era of those units,” mission lead Jack Radford says within the article.

Within the not-to-distant future, surgical sufferers might hear “The robotic will see you now,” because the authors of this story recommend. The three researchers work on the Johns Hopkins University robotics lab chargeable for creating Smart Tissue Autonomous Robot (STAR), which carried out the primary autonomous soft-tissue surgery in a stay animal in 2016.
Whereas there are definitely challenges remaining within the quest to carry autonomous robots into the working room—like creating normal goal robotic controllers and amassing information inside strict privateness rules—the top aim is on the horizon. “A state of affairs by which sufferers are routinely greeted by a surgeon and an autonomous robotic assistant is not a distant risk,” the authors write.
