Piezoelectric devices surround us in our everyday life. Our cars and trucks contain many piezoelectric devices, including fuel level sensors, air bag deployment sensors, parking sensors and piezoelectric generators in the wheels to power the tire pressure monitoring system. Your smartphones or tablet contains piezoelectric sensors that detect the motion and orientation of the device, which my kids were using to good effect to play “Need For Speed” yesterday. Many of us have ink jet printers at home, which can use piezoelectric printer heads to eject thousands of drops per second. Continue reading

System-level Approach to Robust ESD Design

The battle is on for manufacturers of automotive, medical, industrial and consumer electronics to drive new innovations, deliver exciting products, and ensure safety and reliability of the devices that proliferate our world. Mobile devices that are intended to interact with our world face unique reliability challenges such as electrostatic discharge (ESD) protection, making a robust ESD design a necessity. While we want our mobile phone, tablet and smartwatch to be “connected” and “interactive”, the number of interface ports on these devices make them vulnerable to an ESD event. Interfaces such as network connectors, USB ports, and antennas need careful planning of the location and size of ESD protection structures. Continue reading

How Bioreactors Are Keeping Cells Happy

Cell-culture bioreactors lie at the heart of the processes used to produce large-molecule, protein-based therapeutics. In cell culture, mammalian cells are grown outside the human/plant body. These cells produce therapeutic proteins and antibodies. This is much easier said than done. In fact, cells do not cooperate much when they are grown outside the (human or plant) body. The question then is: Why is it so difficult for cells in culture to have the same physiological function in laboratory as in our body? Continue reading

Engineering Wearable Technology for the Internet of Things

In terms of dollars, according to the latest forecast from IDC, the Internet of Things (IoT) market will grow to more than $7 trillion, up from $2 trillion today with wearable technology leading the way.
