Unlike standard electro-mechanical relays (EMRs) and contactors which use coils, magnetic fields, springs and a variety of mechanical contacts to control and switch a power supply.  The  Solid State Relay , or  SSR  as it is more commonly known, has no moving parts but instead uses ...

Within 20 years, implantable devices will increasingly incorporate electronics to enable noninvasive assessment. Current cardiac stents simply revascularize arteries; future stents may include sensors that use radio-frequency identification (RFID) to report vessel status wirelessly when scanned over the chest. Sensorized artificial discs will be implanted in the hip, spine, or knee to noninvasively monitor load and verify proper function, as shown in Figure 2. If excessive load or malfunction is detected, the sensors will alert the patient and caregivers so corrective measures can be taken promptly. High-performance sensors have not been widely used in implants because proteins and the immune system can attack devices, limiting long-term efficacy. Over the next 20 years, cellular biology approaches will reduce immune recognition of sensors as foreign bodies. Biocompatible materials will be essential for all implantable devices.  

  CHIPLET-BASED VLSI DESIGN           Chiplet-based VLSI design divides a large System-on-Chip (SoC) into several smaller functional dies called chiplets . Each chiplet performs a specific function and is integrated together inside a single package.

                                                                           ADVANCED FOOTSTEP POWER GENERATION SYSTEM      An Advanced Footstep Power Generation System is a renewable-energy system that converts the mechanical energy produced when a person walks into electrical energy . It is suitable for places with heavy pedestrian movement such as railway stations, bus stands, shopping malls, colleges, hospitals, airports and public walkways. The rapid increase in energy demand and depletion of conventional resources has created an urgent need for alternative and renewable energy solutions. Among various innovative approaches, energy harvesting from human motion has emerged as a promising technique. The Advanced Footstep Power Generation System is a smart renewable energy concept th...
