Researchers Develop a Tiny Temperature Sensor Powered by Radio Waves

first_imgResearchers at TU/e have developed a very tiny wireless temperature sensor that is powered by radio waves that are part of the sensor’s wireless network. This means that the sensor needs not even a single wire, nor a battery that would have to be replaced. This breakthrough has a wide range of applications such as smart building and other Internet of Things applications. The smart buildings of the future will be full of sensors to regulate heating, cooling, lighting and a number of other actions. This new technology makes it possible to operate sensors without any batteries which makes installation and maintenance very easy.The current version of the sensor has a range of 2.5 cm. The researchers expect to extend this to a meter within a year, and ultimately to 5 meters. The sensor has a specially developed router, with an antenna that sends radio waves to the sensors to power them. Both the router and the sensor consume very little electricity. The sensor can also operate beneath a layer of paint, plaster or concrete, which makes it ideal for installation in to building.The sensor contains an antenna that captures the energy from the router. The sensor stores that energy and, once there is enough, the sensor switches on, measures the temperature and sends a signal to the router. This signal has a slightly distinctive frequency, depending on the temperature measured. The router can deduce the temperature from this distinctive frequency.The same technology enables other wireless sensors to be made, for example to measure movement, light and humidity. The researchers expect the cost of the sensors under mass production to be down to down to around 20 cents. The sensor is based on 65-nm CMOS technology.The project, called PREMISS, has received funding from the STW technology foundation. Hao Gao, the researcher behind this project will be awarded his PhD on Monday 7 December for his thesis in which he developed a sensor that measures just 2 square mm and weights a mere 1.6 milligrams, equivalent to a grain of sand. The title of Hao Gao’s thesis is ‘Fully Integrated Ultra-Low Power mm-Wave Wireless Sensor Design Methods’. The integrated circuits research was done in the Mixed-Signal Microelectronics group and also involved the TU/e groups Electromagnetics and Signal Processing Systems as well as the Center of Wireless Technology.last_img read more

PhilHealth’s Morales, del Rosario resign

first_imgPhilHealth president and CEO Ricardo Morales (left) and senior vice president for legal sector Rodolfo del Rosario Jr. (right) have tendered their resignation on Wednesday amid ongoing investigations of corruption and fraud in the agency.RAPPLER “The past days have been so grueling and stressful. The character assassination, trial by publicity, and relentless persecution have left me in so much agony. My six-month suspension was too much to bear,” Del Rosario said in his Facebook post. Morales maintained that there is not “an iota of evidence” that would link him to the alleged irregularities at PhilHealth, specifically with regards to the interim reimbursement mechanism (IRM) and the overpricing of an IT system. MANILA – Philippine Health Insurance Corp. (PhilHealth) president and CEO Ricardo Morales and senior vice president for legal sector Rodolfo del Rosario Jr. have resigned on Wednesday. Del Rosario, meanwhile, resigned as the trial by publicity that congressional inquiries on alleged corruption in PhilHealth, coupled with the six-month preventive suspension slapped by the Office of the Ombudsman, put him in so much agony. “As I cannot afford to be unemployed for the next six months and understanding that the corporation would need an SVP Legal in these trying times, I have tendered my irrevocable resignation effective August 24, 2020. This was a painful decision,” he added. “Para akong nabunutan ng tinik,” Morales said on his resignation. “Malaki ang pasalamat ko sa pangulo natin. He never wavered in his confidence in me. I’m so humbled by his loyalty.” Morales said in a radio interview on Wednesday morning that he submitted a hard copy of his resignation letter to Executive Secretary Salvador Medialdea after being told by President Rodrigo Duterte to resign due to his health condition. PhilHealth has been under multiple investigations over its release of P15 billion advance payments to hospitals and health care institutions amid COVID-19 of which only P1 billion was accounted for, alleged overpriced IT project, overpayments of reimbursements to hospitals, among others./PNlast_img read more

Can they topple England?

first_imgOn the back of the Hunters’ success in taking out the Queensland Cup this season, PNG veteran Paul Aiton has given the national side an on-par chance of sending England home early.Speaking from Melbourne, Aiton said it’s a 50-50 as far as the Kumuls are concerned; they are training to win!PNG coach Michael Marum has left out Lachlan Lam following his sensational two-try debut against the United States, opting for experience in the halves with Ase Boas.Boas, 27, proved he can handle the clutch moments of big games when he helped deliver the PNG Hunters their maiden Queensland Cup title back in September.He’ll play alongside 23-year-old brother Watson in the halves on Sunday. They also played a starring role in the Hunters’ breakthrough season.The last time the two sides met was at the 2010 Four Nations, where the Kumuls went down 36-10 at Eden Park in New Zealand. Before that was at the 2008 World Cup in Townsville, where it was just a 32-22 England victory.Having played all their games on home turf, the shift to Melbourne Rectangular Stadium presents a challenge in itself, but the majority of the squad should be well-versed with playing abroad.England’s showstoppers Ryan Hall and Jermain McGillvary will oppose Justin Olam and PNG’s leading try-scorer Garry Lo.With a domestic cup already in their hands and an undefeated run so far, this suggests that the Kumuls are a far better side than the one England beat some odd 9 years back.(PNG veteran Paul Aiton)last_img read more
