A new line of fingertip sensors measures pressures that are difficult to gauge by conventional means.
FingerTPS tactile pressure sensors, from Pressure Profile Systems Inc., Los Angeles, are worn on a person's fingertips and palm to measure the pressures exerted while using a tool or performing some other action.
Applications could range from recording a pianist, to training medicalhealth practitioners in proper palm or finger pressures for infant CPR, to designing a better tool handle or computer mouse. The system could also quantify what has been an entirely subjective measurement pain by objectively determining the sensitivity of injured tissues to touch, as might be done for burn victims.
Based on capacitive-sensor technology, the sensors measure pressures up to 10 lb in 0.1-lb increments. Less than 2-mm thick, they are mounted in stretchable fabric for a snug fit on the user's fingers. The systems are USB powered and supported by PC-resident software, which displays and tracks time-series, average, and peak pressures.
