3D Printed Plastics with High-Performance Electrical Circuits

  • Magazine Article
  • TBMG-35771
Published 2020-01-01 by Tech Briefs Media Group in United States

Engineers have embedded high-performance electrical circuits inside 3D printed plastics, which could lead to better-performing biomedical implants. They used pulses of high-energy light to fuse tiny silver wires, resulting in circuits that conduct 10 times more electricity than the state of the art. By increasing conductivity tenfold, the engineers can reduce energy use, extend the life of devices. and increase the device’s performance.

Implants: Protective Membrane Reduces Tissue Buildup

  • Magazine Article
  • TBMG-35775
Published 2020-01-01 by Tech Briefs Media Group in United States

Scientists have developed a special protective membrane made of cellulose that significantly reduces the buildup of fibrotic tissue around cardiac pacemaker implants, as reported in a recent issue of the journal Biomaterials.1 The protective membrane could greatly simplify surgical procedures for patients with cardiac pacemakers.

Embedding Artificial Muscles into Soft Materials

  • Magazine Article
  • TBMG-35785
Published 2020-01-01 by Tech Briefs Media Group in United States

Stretchable skin-like robots that can be rolled up and put in your pocket have been developed by a team using a new way of embedding artificial muscles and electrical adhesion into soft materials. This new advance could create new thin and light robots for wearable technologies.

Wireless Sensor “Stickers” Track Physiological Signals

  • Magazine Article
  • TBMG-35823
Published 2020-01-01 by Tech Briefs Media Group in United States

Engineers have developed a way to detect physiological signals emanating from the skin with sticky sensors that beam wireless readings to a receiver clipped onto clothing. To demonstrate the wearable technology, the researchers stuck sensors to the wrist and abdomen of a test subject to monitor the person's pulse and respiration by detecting how their skin stretched and contracted with each heartbeat or breath. Likewise, stickers on the person's elbows and knees tracked arm and leg motions by gauging the minute tightening or relaxation of the skin each time the corresponding muscle flexed.

Wirelessly Controlled Ingestible Capsule

  • Magazine Article
  • TBMG-35789
Published 2020-01-01 by Tech Briefs Media Group in United States

Researchers have developed an ingestible capsule that can be controlled using Bluetooth wireless technology. The capsule — which can be customized to deliver drugs, sense environmental conditions, or both — can reside in the stomach for at least a month, transmitting information and responding to instructions from a user's smartphone.

Microchip Produces High-Contrast OCT Imagery

  • Magazine Article
  • TBMG-35758
Published 2020-01-01 by Tech Briefs Media Group in United States

Scientists at Columbia University, New York, have used a microchip to map the back of the eye for disease diagnosis. The interference technology used in the microchip — like bat sonar but using light instead of sound waves — has been around for a little while. However, this is the first time that technical obstacles have been overcome to fabricate a miniature device able to capture high quality images.

Micro Device Detects Ebola Virus Using Bio-Sensors

  • Magazine Article
  • TBMG-35801
Published 2020-01-01 by Tech Briefs Media Group in United States

A prototype micro device with biosensors was developed that can detect the deadly Ebola virus. With this type of device, those infected can be treated earlier, and the early detection process can potentially decrease the spread of infections.

5 Ws of 3D Modeling for the Visually Impaired

  • Magazine Article
  • TBMG-35805
Published 2020-01-01 by Tech Briefs Media Group in United States

Creating a 3D object with computer software is often the first step in producing it physically. Even with 3D modeling software that has more accessible ways of inputting designs, the visually impaired or blind still have to evaluate their work by either creating a physical version they can touch or by listening to a description provided by a sighted person.
