ELECTRONICS/SENSORS: Honeywell has expanded its ASDX plastic silicon pressure sensor family with the new ASDX Series and ASDX-DO Series, which offer pressure ranges from 1 psi to 5 psi. Onboard signal conditioning allows the customer to remove those components from their PC board to free space, may reduce their acquisition, inventory and assembly costs, and minimize potential problems from having multiple signal conditioning components spread across a circuit board. These low-pressure sensors are intended for use with non-corrosive, non-ionic working fluids, such as air and dry gases. Potential industrial and medical applications include barometry, flow calibrators, gas-flow instrumentation, sleep apnea/therapy equipment, pneumatic controls and ventilation/airflow monitors. The ASDX and ASDX-DO Series pressure sensors are fully calibrated and temperature compensated for sensor offset, sensitivity, temperature effects, and non-linearity using an on-board Application Specific Integrated Circuit (ASIC). Calibrated output values for pressure are updated at approximately 1 kHz.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
