It is well known that the best switching element is a relay. It has the best linearity, lowest insertion losses, maximum bandwidth, and maximum voltage & power handling capabilities. And if it is an electrostatic MEMS relay, it also has minimum power consumption.

Therefore, why are not all chips made full of micro-relays inside them? The answer is that, if they must be activated from low voltage control signals, nobody knows how to place thousands of them inside a single chip die.

Well we know how to do it at Baolab Microsystems, and this opens up the possibility for many new electronic systems not feasible until now...
