Researchers from the University of Utah are developing a system that allows amputees to control a bionic arm using just their thoughts. What’s more, the hand portion of the limb enables them to ‘feel’ objects that are being touched or grasped. Known as the Luke Arm (a tribute to Luke Skywalker’s prosthetic limb), the robotic arm mimics the way a human hand feels different objects by sending signals to the brain. An amputee wearing the arm can sense how hard or soft an object is, letting them understand how best to handle said objects.
Imagine if there were a metallic device that could be transported all squished down into a compact ball, but that would automatically “bloom” out into its useful form when heated. Well, that may soon be possible, thanks to a newly developed liquid metal lattice.
Led by Asst. Prof. Pu Zhang, a team of scientists at New York’s Bingham University started by 3D printing lattice-type structures out of an existing metal known as Field’s alloy. Named after its inventor, chemist Simon Quellen Field, the alloy consists of a mixture of bismuth, indium and tin. It also melts when heated to just 62 °C (144 °F), but then re-solidifies upon cooling.
Utilizing a combination of vacuum casting and a technique known as conformal coating, those alloy lattices were subsequently covered with a layer of rubber. As long as the ambient temperature stayed below 62 degrees, the resulting structures remained rigid.
When you imagine an exoskeleton, chances are it might look a bit like the Guardian XO from Sarcos Robotics. The XO is literally a robot you wear (or maybe, it wears you). The suit’s powered limbs sense your movements and match their position to yours with little latency to give you effortless superstrength and endurance—lifting 200 pounds will feel like 10.
A vision of robots and humankind working together in harmony. Now, isn’t that nice?
A Korean research team has developed a lithium-ion battery that is flexible enough to be stretched. Dr. Jeong Gon Son’s research team at the Photo-Electronic Hybrids Research Center at the Korea Institute of Science and Technology (KIST) announced that they had constructed a high-capacity, stretchable lithium-ion battery. The battery was developed by fabricating a structurally stretchable electrode consisting solely of electrode materials and then assembling with a stretchable gel electrolyte and stretchable packaging.
Rapid technological advancements in the electronics industry have led to a fast-growing market for high-performance wearable devices, such as smart bands and body-implantable electronic devices, such as pacemakers. These advancements have considerably increased the need for energy storage devices to be designed in flexible and stretchable forms that mimic human skin and organs.
However, it is very difficult to impart stretchability to the battery because the solid inorganic electrode material occupies most of the volume, and other components such as current collectors and separators must also be made stretchable. In addition, the problem of liquid electrolyte leakage under deformation must also be solved, as well as the problem of leaking liquid electrolyte.

Researchers at Technische Universität München in Germany have recently developed an electronic skin that could help to reproduce the human sense of touch in robots. This e-skin, presented in a paper published in MDPI’s Sensors journal, requires far less computational power than other existing e-skins and can thus be applied to larger portions of a robot’s body.
“Our main motivation for developing the e-skin stems from nature and is centered on the question of how we humans interact with our surrounding environment,” Florian Bergner, one of the researchers who carried out the study, told TechXplore. “While humans predominantly depend on vision, our sense of touch is important as soon as contacts are involved in interactions. We believe that giving robots a sense of touch can extend the range of interactions between robots and humans—making robots more collaborative, safe and effective.”
Bergner and other researchers led by Prof. Gordon Cheng have been developing e-skins for approximately ten years now. Initially, they tried to realize e-skin systems with multi-modal sensing capabilities resembling those of human skin. In other words, they tried to create an artificial skin that could sense light touch, pressure, temperature, and vibrations, while effectively distributing its sensing across different places where tactile interactions occurred.
A research collaboration and ensuing friendship between a trauma surgeon in Oregon and a handful of engineers in Florida has resulted in a new ventilator design that requires no electricity and could be a game-changer during the COVID-19 pandemic.
Albert Chi, who specializes in critical care and prosthetics, was keeping a close eye on COVID-19 during the early days. He immediately began working with his team at Oregon Health and Science University to develop a new, easy way to replicate ventilators that could be deployed anywhere. Specializing in trauma, Chi as a retired commander of the U.S. Navy Reserve and well versed in extreme conditions.
When Chi had a design, he called his friend and clinical-trial collaborator Albert Manero CEO and co-founder of Limbitless Solutions in Orlando, Florida.
Existing electronic skin (e-skin) sensing platforms are equipped to monitor physical parameters using power from batteries or near-field communication. For e-skins to be applied in the next generation of robotics and medical devices, they must operate wirelessly and be self-powered. However, despite recent efforts to harvest energy from the human body, self-powered e-skin with the ability to perform biosensing with Bluetooth communication are limited because of the lack of a continuous energy source and limited power efficiency. Here, we report a flexible and fully perspiration-powered integrated electronic skin (PPES) for multiplexed metabolic sensing in situ. The battery-free e-skin contains multimodal sensors and highly efficient lactate biofuel cells that use a unique integration of zero- to three-dimensional nanomaterials to achieve high power intensity and long-term stability. The PPES delivered a record-breaking power density of 3.5 milliwatt·centimeter−2 for biofuel cells in untreated human body fluids (human sweat) and displayed a very stable performance during a 60-hour continuous operation. It selectively monitored key metabolic analytes (e.g., urea, NH4+, glucose, and pH) and the skin temperature during prolonged physical activities and wirelessly transmitted the data to the user interface using Bluetooth. The PPES was also able to monitor muscle contraction and work as a human-machine interface for human-prosthesis walking.
Recent advances in robotics have enabled soft electronic devices at different scales with excellent biocompatibility and mechanical properties; these advances have rendered novel robotic functionalities suitable for various medical applications, such as diagnosis and drug delivery, soft surgery tools, human-machine interaction (HMI), wearable computing, health monitoring, assistive robotics, and prosthesis (1–6). Electronic skin (e-skin) can have similar characteristics to human skin, such as mechanical durability and stretchability and the ability to measure various sensations such as temperature and pressure (7–11). Moreover, e-skin can be augmented with capabilities beyond those of the normal human skin by incorporating advanced bioelectronics materials and devices.
