Designing a wireless communication system for smart sensor shorts in football: Using lossless data compression and pattern diversity

Decreasing injuries in football is a topic of interest for the KNVB and KNHB. To reach this goal, the use of smart sensor pants is researched. The data will be used to develop models for finding injury risk factors that are related to movements. Currently, the system is capable of reading out the IMUs and storing the data on an SD-card, for post...

From Silicon toward Silicon Carbide Smart Integrated Sensors

Compact Thermal Diffusivity Sensors for On-Chip Thermal Management

Today’s systems-on-chip (SOCs) and microprocessors are complex systems that require multiple temperature sensors to monitor temperature variations in multiple spots on a single silicon die. For such thermal management applications, specialized compact and fast temperature sensors are required. This is necessary because executing an intensive...

A semi-physical platform for guidance and formations of fixed-wing unmanned aerial vehicles

Unmanned Aerial Vehicles (UAVs) have multi-domain applications, fixed-wing UAVs being a widely used class. Despite the ongoing research on the topics of guidance and formation control of fixed-wing UAVs, little progress is known on implementation of semi-physical validation platforms (software-in-the-loop or hardware-in-the-loop) for such...

A 10 fJ·K ²Wheatstone Bridge Temperature Sensor with a Tail-Resistor-Linearized OTA

This article describes a highly energy-efficient Wheatstone bridge temperature sensor. To maximize sensitivity, the bridge is made from resistors with positive (silicided diffusion) and negative (poly) temperature coefficients. The bridge is balanced by a resistive (poly) FIR-DAC, which is part of a 2nd-order continuous-time delta-sigma...

A 0.25 mm²-Resistor-Based Temperature Sensor With an Inaccuracy of 0.12 °C (3σ) From -55 °C to 125 °C

This paper describes a compact, energy efficient, resistor-based temperature sensor that can operate over a wide temperature range (-55 °C-125 °C). The sensor is based on a Wheatstone bridge (WhB) made from silicided poly-silicon and non-silicided poly-silicon resistors. To achieve both area and energy efficiencies, the current output of the WhB...

Smart sensors in asphalt: monitoring key process parameters during and post construction

The Fibre Bragg Gratings (FBG) technology based on integrated photonics, offers specific benefits including thermal mapping, damage detection, shape- and distributed sensing. This makes it useful for determining pavement behaviour during extreme weather conditions e.g. freeze-thaw cycles when harsh winter conditions could damage the asphalt...

Smart wound patch: Design of an integrated electronic sensor system for continuous wound monitoring

Worldwide ca. 20 million patients are suffering from slow- or non-healing wounds. These problematic wounds have a major impact on the mortality risk, quality of life and mobility of patients. Moreover, non-healing wounds are a major financial burden for health care providers. Currently, wound treatments are selected mainly based on visual...
