I require a circuit design and prototype for a medical device that will convert hand grip pressure on a cylindrical object constructed of medical grade silicone to a LED Readout. The LED 5-bar readout will have red red amber amber green indicator of handgrip pressure on the cylindrical silicone bar. The bar readouts will indicate levels of pressure from soft (bottom red) to firm (green) Actuation of the sensor/readout will occur on application of pressure. De-activation will occur ~60 seconds after last activity. The power source will be a button battery. The construct must use smallest possible components. The sensor must operate being encased in Medical Grade Silicone. As it is a medical device, the sensor must be able to tolerate (in off state) 140 degrees Celcius in an Autoclave. The LED readout and power and MCU circuit will be detatchable to avoid autoclave. The force range would be 0 - 100kpa, and the sensor preferably must be cylindrical and measure lateral forces on the cylinder of med grade silicone. This will be used to measure grip strength of infants. Smaller is better. The sensor should read approx 0 - 100KPa.
A sensor range need to be indicated due to dampening of the force due to the Silicone. That is - the grip strength will be 0 - 100kpa, but I need to be able to interchange the sensor to accommodate the dampening effect of the Silicone till I get an appreciable reading. The other way that this could be acheived is calibrating the MCU to account for the loss of sensitivity or having an adjustable sensitivity.
The bid will include 1 Comprehensive Circiut Design and component list with specs, 2 Working Prototype (not including silicone encasement) 3 Posting the prototype to Canberra Australia - Address to be supplied to winning bid.
Presently I am doing a project similar to this, in fact we developed a grip kind mechanism (almost similar to your requirement) to test and calibrate the sensor assembly by holding and squeezing. I have 6+years experie Daha Fazla

We can develop it using a PIC32 and a SCP1000 pressure sensor by Sensirion. Please take a look at [url removed, login to view] for some reference app using such sensor, for instance "Pro-Meteo" weather station.
I actually worked the last 6 months on a system with very similar needs in measuring pressure. Somehow I would suggest to detach sensor+electronics for the autoclave (because of contact issues sensorelectronics) Othe Daha Fazla

Hello, Pls. see the PMB for details. Best Regards, Miki
This seems like a simple project, assuming the cylinders are easy to manipulate.
