“…We associate the current value at which the microheater fails to the melting temperature of platinum (1768 °C). The melting point of thin films for a thickness >50 nm is equivalent to the bulk values [47,48]. We took the melting temperature and the corresponding power that led to failure of the heater as one calibration point (burn-through), and room temperature as second calibration point.…”

Micro/nano thermogravimetry (TG) employing MEMS has significant potential to improve the minimum sample mass and mass resolution as compared to commercial TG instruments. Although there have been a few previous reports on MEMS TG, none of them have critically analysed the obtained TG curve in detail. In this work, we have designed and fabricated a microelectromechanical thermogravimetric device (MMTG) with integrated microheaters and temperature sensors. The mass sensitivity of the device was estimated to be 0.89 pg Hz −1 which outperforms the standard TG approaches. We tested the MMTG performance with CuSO 4 •5H 2 O crystals. The final mass loss ratio corresponds to the theoretically expected value, although the obtained TG curve deviated from the standard TG curve of CuSO 4 •5H 2 O obtained from commercial TG instruments. We attributed the deviation to the inherent temperature non-uniformity, non-isothermal conditions and temperature gradients of metallicwire based microheaters. Finite element (FE) simulations were carried out in order to confirm and gain insights into the non-uniform heating phenomena of microheater and sample. Based on the simulation results, we propose designs that can be realized to make MEMS TG a successful enterprise.
