Prof. Kevin Chen and his colleagues have developed a bee-like robot that can assist with farming practices, such as artificial pollination without damaging crops, reports Claire Turrell for Offrange. “Chen’s robot bee, which is tethered to a power source, is currently limited to flying between plastic flowers in the lab, but the robot engineer can see its potential,” explains Turrell. “Bees are doing great in terms of open-field farming,” says Chen. “But there is one potential type of pollination I think we can consider in the longer term, which is indoor farming,” 

Prof. Jonathan How and graduate student Yi-Hsuan (Nemo) Hsiao speak with Tech Briefs reporter Andrew Corselli about their latest work developing an aerial microrobot that is “agile enough complete 10 consecutive somersaults in 11 seconds, even when wind disturbances threatened to push it off course.” Hsiao explains that: “This work demonstrates that soft and microrobots, traditionally limited in speed, can now leverage advanced control algorithms to achieve agility approaching that of natural insects and larger robots, opening up new opportunities for multimodal locomotion.” 

In a roundup of the biggest tech breakthroughs of 2025, Forbes reporter Alex Knapp spotlights how MIT engineers developed magnetic transistors, a “discovery [that] could enable faster and more energy-efficient semiconductors.”

Researchers at MIT have developed microscopic devices that “can travel autonomously through the blood and provide electrical stimulation to precise brain regions,” and could one day be used to treat brain diseases, mental illness, or other parts of the body, reports Zoe Kriegler for Medical Design & Outsourcing. The development of microscopic wireless electronic devices (SWEDs) could “eliminate the need for brain surgery in some cases, decreasing the risk to the patient and the expense of the procedure by hundreds of thousands of dollars,” Kriegler explains. 

Prof. Deblina Sarkar speaks with Forbes reporter William A. Haseltine about her work developing “circulatronics,” microscopic electronics devices that could one day be used to help treat brain diseases. “What we have developed are tiny electronic devices that can travel through body fluids and autonomously find their target regions, with no external guidance or imaging,” explains Sarkar. “They provide very precise electrical stimulation of neurons without the need for surgery.” 

MIT researchers have developed “GelSight,” a system that provides robots with a sense of touch, reports Ben Guarino for Scientific American. “GelSight can identify by touch the tiny letters spelling out LEGO on the stud of a toy brick,” explains Guarino. 

Prof. Kevin Chen and his colleagues have designed a tiny, insect-sized aerial microrobot that is “faster and more acrobatic than any of its predecessors,” reports Phie Jacobs for Science. The device, “which measures just 4 centimeters across and weighs less than a paperclip, flies almost five times faster and accelerates twice as quickly as existing microrobots,” explains Jacobs. “It can also execute sharp turns while enduring 160-centimeter-per-second wind gusts and—perhaps most impressively—can complete 10 consecutive somersaults in 11 seconds.” 

Graduate student Chung-Tao (Josh) Chou speaks with Tech Briefs reporter Andrew Corselli about his work developing a magnetic transistor that could lead to more energy-efficient circuits. “People have known about magnets for thousands of years, but there are very limited ways to incorporate magnetism into electronics,” says Chou. “We have shown a new way to efficiently utilize magnetism that opens up a lot of possibilities for future applications and research.”

Prof. Steve Leeb and graduate student Daniel Monagle speak with Tech Briefs reporter Edward Brown about their work “designing an energy management interface between an energy harvesting source and a sensor load that will give the best possible results.” Monagle notes that in the future they hope to make the system “smaller so that it can fit in tight places like inside a motor terminal box. But beyond that we want to take advantage of AI tools to design techniques for minimizing the energy used by the system.” 

Researchers at MIT have developed magnetic transistors, “which could enable faster and more energy-efficient semiconductors,” reports Alex Knapp for Forbes. “Researchers have been trying to use magnets this way for years, but the materials used so far haven’t been optimal for computing functions,” explains Knapp. “That changed after experimenting with chromium sulfur bromide, which replaces the silicon in a conventional microchip and enables the transistors to be switched on and off with an electric current.” 

CNN visits the lab of Prof. Kevin Chen to learn more about his group’s work developing a bee-like robot that can flap its wings up to 400 times a second and flip and hover, and a grasshopper-inspired robot that can hop 20 centimeters into the air in terrains ranging from grass to ice. Chen and his colleagues hope the insect-inspired robots could one day help with tasks like artificial pollination or search and rescue operations. Insects have “evolved for millions of years. There’s a lot to be learned from insect motion, behavior and structure," Chen explains.

WBUR reporter Rachell Sanchez-Smith spotlights two health tech devices being developed by Prof. Yoel Fink and Prof. Canan Dağdeviren, respectively, that aim to “give the wearers — and their doctors — a clearer picture of their overall health.” Fink has created “a thread capable of storing data, running artificial intelligence algorithms, sensing motion and sound, and communication through Bluetooth,” while Dağdeviren’s wearable ultrasound scanner can be used to make breast cancer screening “more comfortable and more accurate,” explains Sanchez-Smith.  

Researchers at MIT have “developed an antenna that can adjust its frequency range by physically changing in its shape” reports Mrigakshi Dixit for Interesting Engineering. “Instead of standard, rigid metal, this antenna is made from metamaterials — special engineered materials whose properties are based on their geometric structure,” explains Dixit. “It could be suitable for applications like transferring energy to wearable devices, tracking motion for augmented reality, and enabling wireless communication.”

Researchers at MIT have designed a new chip component that can “expand the reach of the Internet of Things into 5G,” reports Margo Anderson for IEEE Spectrum. “The discovery represents a broader push for 5G-based IoT tech—using the telecom standard’s low latency, energy efficiency, and capacity for massive device connectivity,” explains Anderson. “The new research also signals an important step toward applications that include smaller, low-power health monitors, smart cameras, and industrial sensors, for instance.” 

Researchers at MIT have developed “a new imaging technique that could allow quality control robots in warehouses to peer into closed boxes,” reports Chris Young for Interesting Engineering. “Using this new technology, robots could peer into a cardboard shipping box and see that the handle of a mug is broken, for example,” explains Young. “This new method could revolutionize warehouse quality control and streamline the shipping and delivery process.”
