Improving Prosthetics for Upper Limb Amputees

  • Magazine Article
  • TBMG-36239
Published 2020-03-01 by Tech Briefs Media Group in United States

New machine learning algorithms and computational models may provide insight into the mental demand placed on individuals using prosthetics. These models will improve the current interface in prosthetic devices.

Stretchable Wireless Sensor Could Monitor Healing of Cerebral Aneurysms

  • Magazine Article
  • TBMG-36149
Published 2020-03-01 by Tech Briefs Media Group in United States

The stretchable sensor, which operates without batteries, would be wrapped around stents or diverters implanted to control blood flow in vessels affected by the aneurysms. To reduce costs and accelerate manufacturing, fabrication of the stretchable sensors uses aerosol jet 3D printing to create conductive silver traces on elastomeric substrates. The 3D additive manufacturing technique allows production of very small electronic features in a single step, without using traditional multi-step lithography processes in a cleanroom. The device is believed to be the first demonstration of aerosol jet 3D printing to produce an implantable, stretchable sensing system for wireless monitoring.

Soft, Conformable Hearing Implants

  • Magazine Article
  • TBMG-36159
Published 2020-03-01 by Tech Briefs Media Group in United States

Close to half a million people around the world suffer from a serious hearing impairment. In some cases, they can find relief in cochlear and other types of implants. Yet these devices do not help people whose inner ear is damaged or whose auditory nerve does not function properly. For these patients to recover their sense of hearing, electrical signals must be sent directly to the auditory brainstem. The neuroprosthetic used for this purpose is called an auditory brainstem implant (ABI); however, the outcomes of ABIs are mixed and in many cases, patients recover only sound perception. Clinical ABIs are also stiff and cannot conform precisely to the curvature of the auditory brainstem.

Wireless System Powers Devices Inside the Body

  • Magazine Article
  • TBMG-36169
Published 2020-03-01 by Tech Briefs Media Group in United States

In the brain, implantable electrodes that deliver an electrical current are used for a technique known as deep brain stimulation, which is often used to treat Parkinson’s disease or epilepsy. These electrodes are now controlled by a pacemaker-like device implanted under the skin, which could be eliminated if wireless power is used. Wireless brain implants could also help deliver light to stimulate or inhibit neuron activity through optogenetics, which so far has not been adapted for use in humans but could be useful for treating many neurological disorders.

Engineers Design Bionic ‘Heart’ for Testing Prosthetic Valves, Other Cardiac Devices

  • Magazine Article
  • TBMG-36262
Published 2020-03-01 by Tech Briefs Media Group in United States

As the geriatric population is expected to balloon in the coming decade, so too will rates of heart disease in the United States. The demand for prosthetic heart valves and other cardiac devices — a market that is valued at more than $5 billion dollars today — is predicted to rise by almost 13 percent in the next six years.

Q&A: Solid Silk - A Biocompatible, Sustainable, Degradable Building Block

  • Magazine Article
  • TBMG-36175
Published 2020-03-01 by Tech Briefs Media Group in United States

David Kaplan, Stern Family Professor of Engineering at Tufts University’s College of Engineering, and his team have developed a unique and practical method for processing silk into solid form for products such as rods and plates for medical implants.

Welding Ceramics with Lasers

  • Magazine Article
  • TBMG-35992
Published 2020-02-01 by Tech Briefs Media Group in United States

Ceramics have been challenging to weld together because they need extremely high temperatures to melt, exposing them to extreme temperature gradients that cause cracking. Ceramic materials are biocompatible, extremely hard, and shatter-resistant, making them ideal for biomedical implants and protective casings for electronics.

3D Printing of Plastics with Electrical Circuits

  • Magazine Article
  • TBMG-35973
Published 2020-02-01 by Tech Briefs Media Group in United States

Engineers have embedded high-performance electrical circuits inside 3D-printed plastics, which could lead to smaller and versatile drones and better-performing small satellites, biomedical implants, and smart structures.

Multimaterial Fiber “Ink” for 3D-Printed Devices

  • Magazine Article
  • TBMG-35975
Published 2020-02-01 by Tech Briefs Media Group in United States

A new method uses standard 3D printers to produce functioning devices with the electronics already embedded inside. The devices are made of fibers containing multiple interconnected materials that can light up, sense their surroundings, store energy, or perform other actions.

‘Hyper Glue’ Could Be Used for Medical Implants

  • Magazine Article
  • TBMG-36015
Published 2020-02-01 by Tech Briefs Media Group in United States

Researchers hope to make everything from protective clothing to medical implants stronger and more corrosion resistant thanks to a newly developed hyper glue formula. The team of chemists and composite materials researchers discovered a broadly applicable method of bonding plastics and synthetic fibers at the molecular level in a procedure called cross-linking. The cross-linking takes effect when the adhesive is exposed to heat or long-wave UV light making strong connections that are both impact-resistant and corrosion-resistant. Even with a minimal amount of cross linking, the materials are tightly bonded.
