How Harvard’s 1,024 robot swarm does what it does

Researchers at Harvard University’s school of engineering have been puzzling over autonomous robot collaboration – in particular, how do you get robots that can only sense a short distance to make something big without an all-seeing eye or central control to direct them.

And recently they have had some…

68020 MPU stays out of the grave

The 68020 microprocessor will live on, with a new package, life thanks to a collaboration between Essex-based e2v and Freescale.

It is now available in a 132pin ceramic quadpack (CERQUAD), pin-to-pin compatible with the original Freescale plastic quad flat package (PQFP).

“This new package option will facilitate…

Design tools support FTDI’s embedded graphics engine

Alpha Micro Components is creating a suite of tools for designing human-machine interfaces (HMIs) using FTDI Chip’s novel EVE embedded graphics controller chips – both the original FT800 and the new FT801 which adds capacitive touch.

FTDI’s EVE chips are novel because they allow 8bit microcontrollers to drive…

Fluid temperature sensor

Vishay has introduced a 4mm diameter immersion sensor for fluid temperature sensing.

Called NTCAIMME3, its stainless steel housing (2mm tip) allows permanent contact with fluids.

Key parameters are:

-25 to +105°C range
1.5s response time
<0.02K/K thermal gradient
+/-1.5°C accuracy.
100mW maximum power…

Stick-on lactate-sensing tattoo becomes bio-battery

US researchers have fabricated sweat-powered batteries, based on lactate-sensing temporary tattoos – skin ‘transfers’ – the team revealed last year.

The battery is bendable and stretchable.

With side-by-side electrodes covering 2x3mm of skin, the batteries can generates 4µW (70µW/cm2) once the person exercises enough to…
