Abstract
A novel design for high-G capacitive MEMS accelerometers that allows for a critically damped dynamical response is presented. The high damping condition is achieved by reducing the mass while keeping a high rigidity of the sensor through a lattice-like mechanical structure. Compared to previously proposed solutions, this design allows for smaller and more reliable sensors.
