We have cheap sensors but with a lot of them you can significantly increase the accuracy of your measurements.
Some of the photons are allowed to escape from the device to serve a purpose such as reading data off a CD or etching a circuit board.
#One benefit of the electrically driven polariton laser is it only needs to be attached to a power supply to emit photons allowing it to be integrated easily with existing semiconductor chips in the future.
Existing infrared detectors use cryogenically cooled semiconductors or thermal detectors known as microbolometers in which changes in electrical resistance can be correlated to temperatures.
#We set out to make an optomechanical thermal infrared detector#says Ertugrul Cubukcu assistant professor at the University of Pennsylvania.#
#Rather than changes in resistance our detector works by connecting mechanical motion to changes in temperature.#
#Other researchers have developed optomechanical infrared sensors based on this principle but their sensitivities have been comparatively low.
so you don t need any additional material to make these antennas#Cubukcu says.##We take the same exact platform
and by patterning it with these nanoscale antennas the conversion efficiency of the detector improves 10 times.#
#Our antennas can be engineered to absorb at any wavelength.##While only a proof-of-concept at this stage future research will demonstrate the device s capabilities as a low-cost way of analyzing individual proteins and gas molecules.

when sending power through the chip. Most chips send their signaling information, which determines if it is sending zeros or ones, at between 1 and 1. 8 volts,
but the Ambiq chip sends its information. 5 volts. That means it uses much less energy overall.

#Tiny new sensor could simplify brain wave research Two years ago, researchers at the National Institute of Standards and Technology (NIST) in the U s. developed a tiny magnetic sensor that could detect the human heartbeat without touching the subject's skin.
Now, the same team has improved the sensitivity of the device tenfold, making it capable of measuring human brain activity
the researchers came up with a magnetic sensor the size of a sugar cube that is also cheaper to manufacture
"Our sensors can be fabricated in parallel with techniques usually adopted for microelectronics, "says Kitching.""Moreover, while SQUID-based imaging systems require a large magnetically-shielded room to operate,
an imaging system based on our sensors could probably be operating in a much smaller (person-sized) shielded enclosure.
an array of over 306 SQUID sensors is mounted in heavy helmet-shaped flasks containing cryogenic coolants.
But the peculiar characteristics of the newly developed sensor might enable lightweight and flexible MEG helmets that contain much fewer sensors."
"We are targeting 32 sensors for our system right now, "says Kitching. The NIST sensor was used to measure alpha waves in the brain associated with a person opening
and closing their eyes as well as signals resulting from stimulation of the hand; the measurements were verified then by comparing them with signals recorded by a SQUID.
The sensor measured magnetic signals of about 1 picotesla (trillionth of a tesla), which is 50 million times weaker than the Earth's magnetic field."
#Inexpensive sensor measures ripeness of fruit As fruit matures, it releases a gas known as ethylene,
inexpensive ethylene sensors that could be used in places such as supermarkets. There, they could let shopkeepers know which batches of fruit need to sold the soonest
each sensor utilizes an array of tens of thousands of carbon nanotubes, which have had copper atoms attached to them.
the sensors are able to determine ethylene levels. As a result, the sensors can reportedly measure concentrations as low as 0. 5 parts per million for context
a concentration of between 0. 1 and one part per million is what is required generally for most types of fruit to ripen.
The sensors were tested on bananas, avocados, apples, pears and oranges, and were able to accurately gauge the ripeness of all of them.
Swager now envisions the sensors being built into the cardboard boxes used to store fruit, and equipped with radio-frequency identification chips that would allow them to transmit ripeness data to handheld reading devices used by shopkeepers.
Each sensor and chip combined should cost about US$1, as opposed to the $1, 200 or so that gas chromatography
or mass spectroscopy systems currently run at. Another system, developed at the UK's National Physical Laboratory, uses radio frequencies, microwaves, terahertz radiation and far-infrared light to determine the ripeness of strawberries
such as the gut-on-a-chip, can therefore significantly accelerate our ability to develop effective new drugs that will help people who suffer from these disorders."
"The gut-on-a-chip is the latest in a series of engineered organ models developed at the Wyss Institute,
which began with the lung-on-a-chip. The institute has received also funding to develop a heart-lung micromachine to test the safety and efficacy of inhaled drugs on the integrated heart and lung function,
and a spleen-on-a-chip to treat sepsis. The team gut-on-a-chip is detailed in the journal Lab on a Chip.

##Researchers at North carolina State university have developed a method to deliver power to moving vehicles using simple electronic components, rather than the expensive power electronics or complex sensors previously employed.
The system uses a specialized receiver that induces a burst of power only when a vehicle passes over a wireless transmitter.
Wireless charging through magnetic induction##the same type typically used for electric toothbrushes##is being pursued by a number of companies for consumer electronics and electric vehicles.
When a car with its own coil is placed above the transmitter, the magnetic field induces a flow of power that charges the batteries.
Stationary inductive chargers for electric vehicles typically use sensors to ensure that the receiver coils on the vehicle are aligned above wireless charging pads correctly.
The NCSU researchers system operates without position sensors in an attempt to simplify the design
the transmitter coil gives off a weak field. But when a vehicle with a receiver passes by

Precisely controlling when the roadway coils produce a magnetic field is important for safety reasons; if the field misses the car s receiving coils,
or contain the magnetic field produced by the transmitter to always be right below the receiver.
In a stationary induction charger, the power receiver is made with a simple coil. The NCSU device is sophisticated more.
The coupling between transmitter and receiver could be done with power electronics but such a system would be more expensive than the NCSU device,
The techniques that the NCSU researchers used for dynamic EV charging have already been applied in some consumer electronics,
