Secure 3D Printing: 'Three-Layer' System Protects Parts from Hackers

A 3D printer is essentially a small embedded computer — and can be exploited like one.

Researchers from Georgia Institute of Technology and Rutgers University have developed a “three-layer” way of certifying that an additively manufactured part has not been compromised.

Sprayable Sensing Network Monitors Structural Health

Sprayed sensors were developed that can be networked to render real-time information on the health status of a structure, detecting hidden flaws. The sprayed nanocomposite sensors and an ultrasound actuator are used to actively detect the health condition of the structure to which they are fixed.

Soft, Stretchy Fabric Sensors Enable Wearable Robots

A highly sensitive, soft, capacitive sensor made of silicone and fabric that moves and flexes with the human body can unobtrusively and accurately detect movement. The technology consists of a thin sheet of silicone sandwiched between two layers of silver-plated, conductive fabric forming a capacitive sensor that registers movement by measuring the change in capacitance.

Researcher Sees the Power of Solar Glasses

New eyeglasses from Germany’s Karlsruhe Institute of Technology generate solar power. Featuring semitransparent organic solar cells, the eyewear powers a microprocessor and two small displays integrated into the solar glasses’ temples. In a Tech Briefs Q&A, one KIT researcher explains why the proof-of-concept is the first step to even smarter devices.

Future Fashion Statement? New Material Generates Power from Human Motion

Vanderbilt University researchers developed an ultra-thin system that can harvest energy from the slightest of human motions — even sitting. Made from materials five thousand times thinner than a human hair, the technology may someday be woven into clothing to power personal devices.

Sound-Off: How Do a Vehicle’s Imaging Sensors Filter Out Weather, Crosstalk?

A "Geiger-mode" lidar sensor sends out pulses at a high repetition rate (200 kHz), forming an image on the percent of pulses that return. The technology has been used by vehicle manufacturers to support collision avoidance, adaptive cruise control, and other Advanced Driver Assistance System (ADAS) applications. But how will factors like snow or another vehicle’s lidar impact a sensor's reading?

One Plug-In Sensor Does Work of Many

Researchers have developed a sensor package that monitors multiple phenomena in a room using machine-learning techniques. The prototype contained 19 different sensor channels, including sensors that indirectly detect sound, vibration, motion, color, light intensity, speed, and direction. The sensor board is plugged in to a wall outlet, eliminating the need for batteries.
