Wearable muscles offer an impressive upper-body endurance boost
Researchers at ETH Zurich have developed a lightweight, wearable textile exomuscle that uses sensors embedded in its fabric to detect a userâs movement intentions and chip in extra force as needed. Initial tests show a significant boost in endurance.
Where powered exoskeletons act as both muscle and bone, providing force as well as structural support, exomuscles make use of the bodyâs own structure and simply chip in with additional force. As a result, theyâre much lighter and less bulky, but theyâre also limited in how much force they can deliver, since human bones and joints can only take so much.
This âMyoshirtâ from ETH Zurich is designed as a vest, with cuffs for the upper arm and forearm. Sensors in the fabric feed data on muscle control impulses to a control box, which processes the information in real time and decides when to actuate the artificial muscles â which are short Dyneema cables aligned parallel with the wearerâs own muscles. By shortening the cables as the muscles contract, the Myoshirt is able to contribute power to your movements in a subtle, discreet, intuitive and tuneable way.

Soon, we wonât need to use the Help function. The computer will sense that we have a problem and come to the rescue by itself. This is one of the possible implications of new research at University of Copenhagen and University of Helsinki.
The Next Generation Of IBM Quantum Computers
IBM is building accessible, scalable quantum computing by focusing on three pillars:
**· **Increasing qubit counts.
**· **Developing advanced quantum software that can abstract away infrastructure complexity and orchestrate quantum programs.
**· **Growing an ecosystem of quantum-ready enterprises, organizations, and communities.
The next step in IBMâs goals to build a frictionless development experience will be the release of Qiskit Runtime in 2022, which will allow developers to build workflows in the cloud, offering greater flexibility. Bringing a serverless approach to quantum computing will also provide the flexibility to distribute workloads intelligently and efficiently across quantum and classical systems.
To help speed the work of developers, IBM launched Qiskit Runtime primitives earlier this year. The primitives implement common quantum hardware queries used by algorithms to simplify quantum programming. In 2023, IBM plans to expand these primitives, as well as the capability to run on the next generation of parallelized quantum processors.

Silicon Quantum Computing announces worldâs first quantum integrated circuit
After a Sydney-based firm built the worldâs first atomic-scale quantum integrated circuit.
Sydney-based firm Silicon Quantum Computing (SQC) built the first integrated silicon quantum computer circuit manufactured at the atomic scale, in what has been touted as a âmajor breakthroughâ on the road to quantum supremacy, a press statement reveals.
The atomic-scale integrated circuit, which functions as an analog quantum processor, may be SQCâs biggest milestone since it announced in 2012 that it had built the worldâs first single-atom transistor.
New Photonic Materials Could Enable Ultra-Fast Light-Based Computing
Researchers at the University of Central Florida are developing new photonic materials which may one day be used to enable ultra-fast, low-power light-based computing. The unique materials referred to as topological insulators, resemble wires that have been flipped inside out, with the insulation on the inside and the current flowing along the exterior.
In order to avoid the overheating issue that todayâs ever-smaller circuits encounter, topological insulators could be incorporated into circuit designs to enable the packing of more processing power into a given area without generating heat.
The researchersâ most recent study, which was published on April 28 in the journal Nature Materials, presented a brand-new process for creating the materials that make use of a unique, chained honeycomb lattice structure. The linked, honeycombed pattern was laser etched onto a piece of silica, a material often used to create photonic circuits, by the researchers.
A Huge Step Forward in Quantum Computing Was Just Announced: The First-Ever Quantum Circuit
Australian scientists have created the worldâs first-ever quantum computer circuit â one that contains all the essential components found on a classical computer chip but at the quantum scale.
The landmark discovery, published in Nature today, was nine years in the making.
âThis is the most exciting discovery of my career,â senior author and quantum physicist Michelle Simmons, founder of Silicon Quantum Computing and director of the Center of Excellence for Quantum Computation and Communication Technology at UNSW told ScienceAlert.
Physicists develop printable organic transistors
Scientists at the Institute of Applied Physics at TU Dresden have come a step closer to the vision of a broad application of flexible, printable electronics. The team around Dr. Hans Kleemann has succeeded for the first time in developing powerful vertical organic transistors with two independent control electrodes. The results have recently been published in the renowned online journal Nature Communications.
High-definition roll-up televisions or foldable smartphones may soon no longer be unaffordable luxury goods that can be admired at international electronics trade fairs. High-performance organic transistors are a key necessity for the mechanically flexible electronic circuits required for these applications. However, conventional horizontal organic thin-film transistors are very slow due to the hopping-transport in organic semiconductors, so they cannot be used for applications requiring high frequencies. Especially for logic circuits with low power consumption, such as those used for Radio Frequency Identification (RFID), it is mandatory to develop transistors enabling high operation frequency as well as adjustable device characteristics (i.e., threshold-voltage). The research group Organic Devices and Systems (ODS) at the Dresden Integrated Center for Applied Photophysics (IAPP) of the Institute of Applied Physics headed by Dr.
