Table 1 Comparison of different types of TAG sensors.
From: Emerging sensing and modeling technologies for wearable and cuffless blood pressure monitoring
Types | Advantages | Disadvantages |
|---|---|---|
Piezocapacitive (without electric double layer) | Suitable for both dynamic/static measurement, environmental stability, long linear range available | Low sensitivity |
Piezocapacitive (with electric double layer) | Suitable for both dynamic/static measurement, environmental stability, high sensitivity available | Trade-off between linear range and sensitivity |
Piezoresistive | Suitable for both dynamic/static measurement, environmental stability, high sensitivity available | Trade-off between linear range and sensitivity |
Piezoelectric | Selfpowered, short linear range | Unsuitable for static measurement, low sensitivity (compared with triboelectric type) |
Triboelectric | Selfpowered, short linear range, high sensitivity (compared with piezoelectric type) | Unsuitable for static measurement, sensitive to humidity |
