An Integrated Energy-Efficient Capacitive Sensor Digital Interface Circuit

In this paper, we propose an energy-efficient 13-bit capacitive sensor interface circuit. The proposed design fully relies on successive approximation algorithm, which eliminates the need for oversampling and digital decimation filtering, and thus low-power consumption is achieved. The proposed architecture employs a charge amplifier stage to acheive parasitic insensitive operation and fine abs...

Capacitive Vibration-to-electricity Energy Converter with Integrated Mechanical Switches

This paper presents the design of a MEMS capacitive vibration-to-electricity energy converter with integrated mechanical switches for precise timing control. Integrated lateral mechanical contact switches have the advantage of zero leakage current, low energy consumption and synchronous operation. The new design can provide an output power of 31μW at a 40V output voltage from the targeted vibra...

An Integrated Tactile-Thermal Robot Sensor With Capacitive Tactile Array

A capacitive tactile sensor and a thermal sensor that can be combined into one compact device with both modalities are illustrated. The tactile sensing portion is composed of an 8 8 array of capacitive cells. By using as thermoresistors the rows’ traces of the matrix of the capacitive tactile array sensor thermal sensing is obtained. This allows the detection of the gradient of the temperature....

Energy breakdown in capacitive deionization.

We explored the energy loss mechanisms in capacitive deionization (CDI). We hypothesize that resistive and parasitic losses are two main sources of energy losses. We measured contribution from each loss mechanism in water desalination with constant current (CC) charge/discharge cycling. Resistive energy loss is expected to dominate in high current charging cases, as it increases approximately l...
