mems04How do you test the sensors in smartphones, smartwatches, and up-and-coming medical devices? With a Femtotools FT-RS1002 Microrobotic System of course! In 2016 the Department of Microelectronics and Nanoelectronics (Faculty of ICT, UoM) set up a slew of devices to be able to to probe, prod and poke devices up to a resolution of 1 nm (thinner  than the diameter of a human hair).

Quick Specs

Number of axes: 3

Maximum velocity: 5 mm/s

Minimum motion increment: 1 nm

Actuation principle: Piezoelectric scanning/stepping

Sensor probe tip area: 50 µm x 50 µm

FT-S100000 sensor force range: ±100000 µN

FT-S100000 sensor resolution at 10Hz: ±5 µN

Operating temperature: 5°C to 100°C

The team of computer scientists collaborated with global semiconductor chip maker ST Microelectronics to p roduce MEMS (Micro-Electro-Mechanical Systems). MEMS are the tiny sensors or devices often found in smartphones that allow them to act like a compass, know how fast a person is going, or detect sound. In Malta, the new equipment is being used to measure mechanical properties (for example shear testing and flexure testing) of tiny mirrors that can be used to turn phones into high-quality projectors (part of the Lab4MEMS2 project part-funded by the EU). This toolkit is incredibly versatile, forming part of a station that can have additional add-ons to widen its applications. Now the team wants to buy more sensitive microforce probes and microgrippers that will allo w the manipulation and assembly of microsystems. This toolkit’s micromechanical testing can be used in many research and industrial applications. This way, the horizon is open for studies into semiconductor technology, microsystem development, materials science, micromedicine, or biotechnology—placing Malta on the semiconductor map.

Dignity in Defiance: A Conversation with Dr Andrè Callus

HUMS marked the conferment of an honorary doctorate on Dr Andrè Callus by inviting him to discuss his activism in detail, shedding light not only on his background but also on the meaning behind the activism. The unique and personal insights offered by Callus illuminate the context within which one of Malta’s leading NGOs operates, and what has made it a success.

A Bird’s-Eye Warning

At the entrance to For Want of (not) Measuring, a contemporary art exhibition, visitors gape at a skull. It is of a bird, but its scale suggests something other. The sculpture rises 2.8 metres above the floor of Spazju Kreattiv in Valletta and balances improbably on its beak atop a column. From some angles, it resembles a fossil; from others, a warning. The work is by Maltese artist Prof. Trevor Borg, titled In the Balance.
