The world’s smallest accelerometer, Wearbral, marks a new era in gaming

In what could be a breakthrough for body sensors and navigation techniques, researchers at KTH developed the smallest accelerometer reported, using a highly conductive nanoscale, graphene.

With each passing day, the potential of nanotechnology and graphene offers new developments.

The latest step is a small accelerometer designed by an international research team consisting of the Royal Institute of Technology KTH, RWTH Aachen University and the Research Institute AMO GmbH, Aachen.

Understandable applications are monitoring systems for cardiovascular diseases and highly sensitive and portable motion capture techniques.

Microelectronic Systems (MEMS) have been the basis for new innovations, for example, in medical technology for decades. Now these systems take them to the next level – the nanoelectric system or NEMS.

Zeus Van, a researcher at the Department of Micro and Nanoscale Systems at KTH, says that Graphene’s unique physical properties enabled it to manufacture these very small accelerometers.

“Based on our surveys and comparisons, we can say that this is the smallest

electromechanical accelerometer ever reported in the world,” says Van. Researchers report their work in Nature Electronics.

The measure by which a conductor is judged by how easy and fast the electrons move through it.

At this stage, graphene, thanks to its exceptional mechanical strength, is one of the most promising materials for an impressive range of applications in electrochemical nanoscale systems.

“We can cut down the components because of the wide thickness of the atomic material and have great electromechanical properties,” Fan says.

“We built the NEMS accelerometer that was designed by the Beatles and is significantly smaller than any MEMS accelerometer available today, but retains the sensitivity required for these systems.”

Van says the future of small accelerometers is promising, comparing advances in nanotechnology to the development of smaller and smaller computers.

“Cell phones may ultimately be useful in navigation, mobile games and pedometer, as well as a cardiovascular monitoring system and mobile devices that can monitor even the slightest movement in the human body.” It said.

Other possible uses of these NEMS adapters include NEMS micro-sensors and triggers such as resonators, gyroscopes, and microphones.

In addition, these NEMS transformers can be used as a system to characterize the mechanical and electrical properties of graphene, Van says.

Max Lamy, a professor at RWTH, is pleased with the results: “Over the years our collaboration with KTH has shown the ability of graphene membranes to compress, Hall sensors and microphones.

We have now added accelerometers to this mix. A few years, so we are working on manufacturing and integration technologies compatible with the industry. ”

To use a microbe within the human body, it must undergo deterioration in vivo or recover after use to minimize additional adverse effects.

As a result, the research team created a micro-robot with a biodegradable polymer and designed it to be biodegradable after its full use.

It can also transport drugs quickly and accurately via wireless control using an external magnetic field.

When a high frequency of alternating magnetic fields is sent to the robot after reaching the desired part of the body, the heat generated by magnetic nanoparticles inside the micro-robot raises the ambient temperature to perform hyperthermia treatment in the target area is given.

One of the major achievements of this research is the ability to release micro-drugs by rotating the time-domain intensity of magnetic fields and exposing them to time.

The research team emphasized the great effectiveness of the treatment of hyperthermia by the use of small robots on cancer cells cultured in the laboratory, and the therapeutic effects of various drug release patterns controlled by alternative magnetic fields.

“We hope to improve cancer treatment through our research, increase the efficiency of cancer treatment and reduce side effects.

By pursuing ongoing research with hospitals and related companies, we have developed will try to do it. Can be used in real medical locations. ”

Anti-cancer treatment is carried out in different ways such as medicines, hyperthermia, radiation and surgery.

Although drug therapy is the most commonly used method among them, it is difficult to accurately deliver the desired volume to a particular part of the body because it is highly dependent on circulatory function.

High body temperature is difficult to reach in a certain part of the body despite its recent popularity due to some side effects.
