Breakthrough Technique Towards 3D Printing Replacement Organs
Directly converting electrical power to heat is easy; however, converting heat into electrical power is not as easy. To address this issue, a tiny silicon-based device was developed that can...
Back pain is inevitable with constrained posture over a number of hours. Permanent damage such as premature spine wear is not uncommon in people who do not adopt proper ergonomic posture. The same applies to those who frequently lift heavy objects.
An ingestible pill was developed that, upon reaching the stomach, quickly swells to the size of a soft, squishy ping-pong ball big enough to stay in the stomach for an...
Silicon nanoneedle patches are currently placed between skin, muscles, or tissues where they deliver exact doses of biomolecules. Commercially available silicon nanoneedle patches are usually constructed on a rigid and opaque silicon wafer. The rigidity can cause discomfort and cannot be left in the body...
An ultra-low-power hybrid chip inspired by the brain could help give palm-sized robots the ability to collaborate and learn from their experiences. Combined with new generations of...
An interdisciplinary Northwestern University team has developed a pair of soft, flexible wireless sensors that replace the tangle of wire-based sensors that currently monitor babies in hospitals’...
Batteries with metallic lithium anodes offer enhanced efficiency compared to conventional lithium-ion batteries because of their higher capacity. However, safety concerns and a short lifespan stand in the way. To...
Stretchable electronics, which can be stretched, deformed and wrapped onto nonplanar curved surfaces, have attracted much attraction due to their...
Simon Fraser University and Swiss researchers are developing an eco-friendly, 3D printable solution for producing wireless Internet-of-Things (IoT) sensors that can be...
Graphene Flagship partner ICFO, based in Barcelona, Spain is developing graphene-based prototypes that aim to turn mobile phones into life saving devices. The first of these will allow...
Anew electromyography biofeedback device that is wearable and connects to novel smartphone games may offer people with incomplete paraplegia a more affordable, self-controllable therapy to enhance...
Light is widely used for communications, carrying phone conversations and video signals through fiber optic cables around the world in pulses composed of many photons. Single...
Researchers devised a method in which running a light emitting diode (LED) with electrodes reversed was able to cool another device nanometers away. They harnessed the chemical potential...
Silicon is a naturally occurring material commonly used as a semiconductor in electronic devices; however, researchers have exhausted the potential of devices with semiconductors made...
The detection of aerosols within fluid samples can be accomplished by optical methods. Such methods are useful in detecting potentially harmful aerosols such as biological aerosols that may be present after a biological agent attack or industrial accident. It is well known that biological molecules fluoresce when...
In discussing fatigue life, it is important to distinguish between disc springs and conical spring washers, as they differ by design and intended usage. Conical spring washers are...
Optical spectroscopy can be used to determine the concentration of chemical species in samples. The amount of light absorbed by a particular chemical species is often linearly related to its concentration through Beer’s Law. For nontransparent materials such as powders,...
Researchers at NASA’s Johnson Space Center improved their Flash Thermography capabilities by incorporating transient and lock-in thermography. By...
Advanced driver-assistance systems and autonomous drive technologies increase the complexity of automotive integrated circuits (ICs), making it harder to ensure that...
Microphones and stethoscopes are regularly used by physicians to detect sounds when monitoring physiological conditions. These monitors are...
The many applications of graphene, an atomically-thin sheet of carbon atoms with extraordinary conductivity and mechanical properties, include the manufacture of sensors. These transform environmental parameters into electrical signals that can be processed and measured with a computer. Due to their...
When engineers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model the flow of air...
Anew type of magnet — called a singlet-based magnet — was discovered that differs from conventional magnets in which small magnetic constituents align with one another to create a strong...
New adversarial techniques developed by engineers at Southwest Research Institute can make objects “invisible” to image detection systems that use deep-learning algorithms. These techniques...
Scientists have taken inspiration from underwater invertebrates like jellyfish to create an electronic skin with similar functionality. Like a jellyfish, the electronic skin is transparent, stretchable, touch-sensitive, and self-healing in aquatic environments.
One of the frontiers of medical diagnostics is the race for more sensitive blood tests. The ability to detect extremely rare proteins could make a life-saving difference for many...
