    摘要： Multiplexed analysis of molecular structures of samples. A plurality of sample wells is arranged on a substrate. A plurality of electrodes is fabricated on a first side of the substrate. The electrodes are disposed on the side of the substrate exposed to the sample wells. The electrodes include working electrodes, counter electrodes, and optionally include reference electrodes. At least two of the sample wells includes a plurality of working electrodes. The plurality of electrodes is configured to allow electrochemical analysis of the associated sample wells in a multiplexed fashion. The plurality of electrodes is electrically coupled to an interface to a sample analysis system. The interface to the sample analysis system can include contacts or connections. The sample analysis system controls a signal to the electrodes in a multiplexed fashion and performs the electrochemical analysis.

    摘要： A micromachined multi-layered microbellows-style actuator capable of delivering larger deflections compared to a single layered flat membrane of comparable size. Anchor structures are disclosed that improve the strength of the microbellows membrane. A characterization apparatus is used to measure microbellows membrane performance. Thermopneumatic actuators having a resistive heater chip are also disclosed. The microbellows membrane is manufactured by alternating deposition of structural layers and sacrificial layers on a substrate. The structural layers can be made of silicon nitride and the sacrificial layers can be made of polysilicon. The substrate is etched from the back to form an opening exposing the sacrificial layers, and then the membrane is released by etching away the sacrificial layers.
