Chipmaker Freescale Semiconductor has created the world’s smallest ARM-powered chip, designed to push the world of connected devices into surprising places. Announced today, the Kinetis KL02 measures just 1.9 by 2 millimeters. It’s a full microcontroller unit (MCU), meaning the chip sports a processor, RAM, ROM, clock and I/O control unit — everything a body needs to be a basic tiny computer. The KL02 has 32k of flash memory, 4k of RAM, a 32 bit processor, and peripherals like a 12-bit analog to digital converter and a low-power UART built into the chip. By including these extra parts, device makers can shrink down their designs, resulting in tiny boards in tiny devices. How tiny? One application that Freescale says the chips could be used for is swallowable computers. Yes, you read that right. “We are working with our customers and partners on providing technology for their products that can be swallowed but we can’t really comment on unannounced products,” says Steve Tateosian, global product marketing manager. The KL02 is part of Freescale’s push to make chips tailored to the Internet of Things. Between the onboard peripherals and a power-management system tuned to the chemistry of current generation batteries, the KL02 is intended to be at the heart of a network of connected objects, moving from shoes that wirelessly report your steps (a natural evolution of Nike ) to pipes that warn you when they are leaking.

A new method of generating terahertz signals on an inexpensive silicon chip could have applications in medical imaging and wireless data transfer. Terahertz radiation, the portion of the electromagnetic spectrum between microwaves and infrared light, penetrates cloth and leather and just a few millimeters into the skin, but without the potentially damaging effects of X-rays. Scanning can identify skin cancers too small to see with the naked eye. Many of the complex organic chemicals used in explosives absorb terahertz radiation at particular frequencies, creating a “signature” that detectors can read. And because higher frequencies can carry more bandwidth, terahertz signals could make a sort of super-Bluetooth that could transfer an entire high-definition movie wirelessly in a few seconds.
