New Components Allow Smaller Phones
Jan 31, 2002, 1:41 PM by (staff)
A University of Michigan professor has developed a new type of tiny resonator using MEMS (micro-electro mechanical systems) technology. Resonators are passive components that sort radio frequencies. Traditionally, the resonator is one of the largest components in a mobile phone's circuitry. The new resonators are thousands of times smaller, and five times more selective, which can lead to phones with smaller batteries as well. Agilent Technologies recently brought a related product to market, with similar beneifts, which is already used by AirPrime and Samsung.
Micro-LED Backlights Could Bring OLED Performance to LCD Screens
AT CES this week, Rohinni demonstrated its micro-LED technology, and provided a glimpse at new backlight technology it's working on for the LCD display panels used in phones. While most LED chips are around 1mm, Rohinni's micro-LEDs are many times smaller and can be placed precisely on thin, flexible plastic sheets.
Samsung Blames Note7 Recall On 2 Battery Problems
Samsung today said problems created during the manufacture of the Galaxy Note7's battery caused the phone to sometimes overheat and burst into flame. The company says two separate battery defects are at fault, but maintains nothing was wrong with the phone itself.
The Galaxy S7 Has Micro-USB for Gear VR
When Samsung's Galaxy S7 and S7 edge were announced this week, many people wondered why the phones have a micro-USB port instead of the newer USB Type-C connector. The competing LG G5 and a growing number of phones at all price points this year include Type-C.
Innovative New Wireless Antenna is Dramatically Smaller
Researchers at Northeastern University have demonstrated a new type of radio antenna that operates in the frequencies used for some cellular networks and Wi-Fi, but is up to 100 times smaller than current antenna designs. The new antenna can be manufactured on a single chip approximately 1mm across.
Samsung Plans to Sell Refurbished Galaxy Note7
Samsung plans to bring back the Galaxy Note7, despite the massive recall that spelled the phone's demise last year. The company will sell refurbished versions of the phone, though Samsung is still determining where via talks with regulatory authorities and carriers.
